Linux

Will my ability to play games be significantly affected compared to Windows?

No*, with options like Wine and Proton (and Lutris and Steam), it's almost a non-existent problem.

*allegedly some games that rely on kernel-level anticheat won't work no matter what workarounds you use. I haven't played these games, so I cannot vouch for it. The games I have played that use anti-cheat have worked fine

Can I mod games as freely and as easily as I do on Windows?

Freely, yes. Easily... depends. E.g. Nexus now has a standalone application that automates installing mods. Setting up this to work with the different games is a bit of learning how Wine works, but it's not terribly frustrating if you have someone helping you understand.

If a program has no Linux version, is it unusable, or are there workarounds?

There are always workarounds, but a very small subset are still unusable. The best option is always to find Free Software alternatives, which there are many more available than there are for windows. Even when that's not an option, there's always Wine, or virtual machines.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

See previous answer.

How do OS updates work in Linux? Is there a “Linux Update” program like what Windows has?

Depends on the OS, but most beginner-friendly distros that are also good long-term distros have an update program like Windows. There are other methods of updating if you go for an immutable distro (like Nix or Guix), but those distros entail less transferable knowledge than distros like Debian or Manjaro.

How does digital security work on Linux?

Same as it works on windows: the weakest link is the user, and the changes they make to the system without understanding the security implications. Which is to say, the strongest security you can have is picking a distro like Debian or Fedora, making no changes to system configuration, and staying up to date on all your updates.

Don't run code you find online without knowing exactly what it's doing behind the scenes, don't follow guides you found online without understanding exactly what each step is doing to your computer.

Is it more vulnerable due to being open source?

No. Why would you think it was?

Is there integrated antivirus software, or will I have to source that myself?

Yes-ish. There are security program that work to protect you in the background (e.g. App Armor and SELinux), but there's no program that actively scans for and detects "malicious activity" like Defender does.

I tend to recommend against these types of active scanning software, as they negatively impact system performance, and they're really only necessary if you're running software from random websites or opening random email attachments or plugging in random usb drives or running random commands you found online.

I can get more in-depth on this, because my job involves setting up systems and maintaining their security, but that's only if you're interested.

Are GPU drivers reliable on Linux?

Yes, but most people have better experience with AMD than Nvidia. They both work, AMD is just a little less finnicky.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

No.

Other people may say otherwise, but that's because it's technically possible on all OSes. It just requires so much special knowledge to even unlock the ability to do so, the odds are astronomically against you ever figuring out how to do so, and you will be warned the entire way down.

And also, what distro might be best for me?

I recommend getting Virtualbox or VMware on windows and setting up and messing around with a few distros people mention as virtual machines to see which one works best for you. The nicest thing about FOSS is the utter freedom you have, so exploring always pays off more in the long run than sticking to a step-by-step guide.

I use Debian: it's easy, it's secure, it's reliable, it's not failed me yet. It's what distros like Linux Mint and Ubuntu are based on. Fedora is also a great mix of reliable, secure, and easy.

I'm happy to get more in-depth on these questions, or really any computing questions you have, I just didn't want to overload you if you weren't looking for a thesis. Feel free to ask me to elaborate though.

I want to add 1 thing....graphics drivers have come a long way. Nvidia is a good example where some diatros come pre loaded to support Nvidia...like popOS. Check your vid card for distro compatibility

1: it’s a cantankerous beast that can smell your fear and lack of computer skills

This can either be true, or not true. It depends on which distro you go with, IMO. There are linux distros specifically designed for new user experiences, and then there are "basic" distros which don't do unnecessary hand-holding for those who are used to the *nix desktop experience.

Making the change has slowly become a more real possibility for me

There has never been a better time to try linux.

I’m pretty much a fairly casual PC-user

If you do light computing, then linux is the best case scenario for you. You won't be changing much about the OS, so not much can go wrong. I installed linux for my 65 year old mother 12 years ago or so, and it's never had an issue. So frankly, I wouldn't worry too much about it.

Will my ability to play games be significantly affected compared to Windows?

As with all things when it comes to linux, it depends. Some of my favorite games have anti-cheat which has no linux client, so therefore even if you can get the game to work in theory, it won't function because no anti-cheat.

If a program has no Linux version, is it unusable, or are there workarounds?

You would be hard pressed to find something which is windows only these days, but even if you do there are virtualization options like WINE or bottles which simulate a windows environment for the application and force it to run under linux anyways.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Sure.

How do OS updates work in Linux? Is there a “Linux Update” program like what Windows has?

Generally, most people use the command line for updating the system itself, but a lot of distributions come with a "Microsoft Store" type application to give you a GUI to update your OS and applications.

How does digital security work on Linux?

Linux works off a multi-user environment which lends security to the OS. You have a root user, which is your super administrative user, and then normal user accounts which can be added as "administrators" which can then run commands and edit files/settings which are reserved for administrative accounts.

Is it more vulnerable due to being open source?

The security is stronger because we know what's in it. Security through obscurity is generally frowned upon, even by NIST.

Is there integrated antivirus software, or will I have to source that myself?

Generally no, but there still are anti-virus available, like ClamWin.

Are GPU drivers reliable on Linux?

My heart says yes, but my fingers won't let me type it.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

It's technically possible, but you would have to meet a laundry list of conditions for that to happen.

And also, what distro might be best for me?

New users seem to really like Mint. But it's exceptionally easy to test different distributions, even directly under Windows using Hyper-V. Test a few out and see if you like em.

And also, what distro might be best for me?

• For gaming and if you just want things to work without being bothered, Nobara. It's a Fedora base, which is good for gaming because you will have updates more quickly than other distros, but not so quick that you will get bad updates breaking stuff. It's Fedora but heavily modified for gaming, and has a lot of stuff already set up that you would need to do manually to improve gaming on another distro. It uses KDE as a Desktop Environment which is pretty good and similar-looking to Windows (a task bar on the bottom, a start menu, a system tray, etc) and you can customize it extensively.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself? Antiwhat ? Just kidding.

• You're not installing softwares by running executables found on random websites, so you at least have less chances of accidentally installing malware that way (not saying that happened to me a lot on Windows... but not saying that it didn't 😅 ).
• The best known antivirus on linux is clamAV, but it's command line only. It's not very complicated to use, but if you want a graphical interface there are several applications that are clamAV frontends (clamAV still does the actual scanning and such, but the application gives you a graphical interface to interact with it)

Will my ability to play games be significantly affected compared to Windows?

• For Steam games, the Steam app has Proton, which enables you to play Windows games on Linux, and most will work just fine. There will always be a few games that require tinkering, or that won't work at all, but not many. You can check ProtonDB to see if your games run well with Proton (https://www.protondb.com/ ) and if a game won't run, you can check it to see if people have posted solutions (sometimes it's as easy as copy-pasting a command into the game's launch options, and poof, there goes the DirectX error !
• For GoG games, and also games from other stores (EA, Epic, etc) you can install Lutris which will use Wine to make your non-Linux games work on linux. As will Proton, there will be a few games that won't cooperate. All in all, I'd say less than 5% of my games don't work or require tinkering, and I have a lot of them.
• If you play multiplayer online games that use kernel-level anticheats, you might be fucked (though I'd argue that it's a good thing, because the game not working is much preferable to the security risk posed by kernel-level anticheats...). Some games are still playable without the anti-cheat activated, you just can't join competitive servers without the anticheat, while other games won't work at all.

I'm only responding to the lack of computer skills portion of the OP as I'm sure others have already answered points plenty and probably better than I could.

If you've used Windows, you have enough basic computer skills to get you started. You'll learn the Linux by using Linux just like you learned Windows by using Windows. There are plenty of mainstream distros that give you an out of the box working experience that is a great starting ground. It does take research and try things out instead of wanting someone to give you the perfect play book.

Will my ability to play games be significantly affected compared to Windows?

Depends on what you play. As a general rule I would say that unless you like competitive multiplayer games you're probably going to be fine. That being said the vast majority of games don't support Linux natively so you need to use workarounds. Steam has a workaround built-in, so if most of your gaming is through Steam it should be an almost seamless transition (all you need to do is enable a checkbook in the settings). But like I said, it depends on what you play, I recommend you check out https://www.protondb.com/ and look for the games you play to see how they run on Linux.

Can I mod games as freely and as easily as I do on Windows?

Same answer as before, if the game runs okay then modding it would also work okay, but if not it might worsen an already bad situation. Also be very careful here, because when you run Windows games on Steam they're sort of sandboxed, i.e. they're running isolated from other stuff, so installing mods is not as straightforward as it would be on windows where binaries are installed globally. It's not a big deal, but just the other day someone was complaining that they installed a launcher needed for a game and the game wasn't finding it and this was the reason.

If a program has no Linux version, is it unusable, or are there workarounds?

As a general rune there's a workaround, it's called WINE (which is an acronym for WINE Is Not an Emulator) which is an "emulator" for Windows (except it's not really an Emulator as the name implies). Then there are some apps built on top of that like Proton (which is what Steam has embebed) that include other libraries and fixes to help. It's not perfect, but unless the program is actively trying to detect it or uses very obscure features on Windows it should work.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Yes, you can use WINE like mentioned above to run Windows binaries that use .NET, but also .NET core is available for Linux.

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

Oh boy, this is the big one, this is the Major difference for m Windows to Linux. Linux has a thing called a package manager, ideally everything you install gets installed via that package manager. This means that everything gets updated together. And here's the thing, we're not talking OS only stuff, new version of the kernel (Linux)? New version of the drivers? New version of Firefox? New version of Spotify? All gets updated together when you update your system. This is crucial to the way Linux works, since it allows Linux to have only one copy of each library. For example, if you have 5 different programs that use the same library, in Windows you'll have 5 copies of that same library, because each program needs their own in the specific version, but in Linux since they will all update together it's easier to have just one library that gets updated together with the programs. This makes maintaining Linux a piece of pie in comparison, just one command or one click of a button and you're all up to date with everything you have installed.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

As a general rule open source programs are more secure than their counterparts. Closed source programs always remind me of Burns going through several security measures, that sort of thing is imposible in open source because if everyone can see all of the security measures, so someone would notice the gaping hole in the back, whereas in closed source only attackers might have found it. Like cyber security experts say: Security by obscurity is not security. As for Antivirus you don't need to worry, Linux is inherently more secure than Windows, and also has a small enough user base (most of whom are security experts) so the number of virus written for Linux is extremely small. Also because you should install stuff through a package manager it's very difficult to get someone to download a bad binary since there's lots of security in the package manager to prevent this sort of thing. In short almost every antivirus program for Linux checks your computer for Windows viruses to avoid being used to store or transmit viruses to Windows computers, so it's completely pointless in your home machine (it's used for example in email servers).

Are GPU drivers reliable on Linux?

Yes... But actually no. It depends, if you have a relatively modern AMD GPU (as in last 10 years) the answer is a resounding YES, AMD currently has wonderful Linux support and their cards work excellently with drivers being fully open source and integrated into the Linux Kernel. For Nvidia the story is unfortunately not as nice. Essentially there are 2 drivers available, nouveau (open source driver written by the community and purposefully hampered by Nvidia) and nvidia (closed source driver written by Nvidia that has gaping incompatibilities with Linux). Since you game your only option is nvidia, while nouveau is great for several reasons it can't match the performance of the nvidia driver. For 99% of stuff the nvidia driver should work fine, but I haven't had good luck with getting Wayland to run on it, which means you're probably stuck in X11 (I know this doesn't mean much to you, but in short it means that you're somewhat limited in your choice for graphical interface and have to use stuff that people are trying to deprecate but can't because of Nvidia)

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

Technically yes, so can Windows by that matter. But realistically no, unless you're writing your own kernel drivers you won't be in any position to cause hardware damage.

And also, what distro might be best for me?

I would probably go with Mint, it's beginner friendly and I've been recommending it for decades. One thing to bear in mind is that in your knowledge level the distro you choose won't make that big of a difference, try to pick something beginner friendly and you should be fine, no need to overthink this.

PS: some extra notes that you didn't asked but I think are good to know:

• Any Linux can look like any other, it's just a matter of installing the right packages
• You should keep your / and /home in separate partitions, this makes it possible for you to reinstall (or even change distros entirely) without losing your files and configuration. This is due to how Linux manages partitions, which in short is not like on Windows where you have a C and D drives but instead any folder can be a different partition or disk.
• You can dual boot, i.e. have 2 OS and choose which one to use every time you turn on your computer.
• You should probably install Linux on a virtual machine first to check it out safely. And do a backup before installing it on your computer just in case you make a mistake.

+1 for Fedora. I recommend Kinoite as it is very similar to windows and very hard to break due to it's "immutability".

Bazzite is very similar to Fedora Kinoite but made to be easy for gaming.

I wont reply point by point because others have already done a fantastic job at that.

Install virtualbox, get some linux images from mint, bazzite or what ever other distro you might want or was recomended and install them as VMs in windows.

Set up a list of things in 3 tiers:

• must have functionalities/workflows (crucial functionality)
• nice to have (important to have)
• optional (can live without)

Then in the installed VMs, test out this list, something like "can I change the volume per app, can I change the audio device per app" or what ever is important to you, according to your list.

This way you can test out if its for you or not, you wouldn't even have to leave windows for it.

One thing regarding gaming, as I game quite a bit too - games with intrusive anticheats dont work, most of everything else works with steam proton. Check potondb.com for your games, you will see what works and what not.

In regard to question one: it depends. Pretty much everything without a shitty, Kernel-Level Anti-Cheat (my autocorrect corrected to antichrist — for good reason!) will run either by default on steam or with something known as Proton. But you still may run into occasional difficulties.

For example, if you play Counter Strike 2: up until January this year, playing on Linux meant ≈20% less performance (CS2 is unoptimized for Linux and Vulkan unfortunately); this number has changed since the last few updates and since the new Nvidia driver, so I need to re-run the benchmarks. Your going to occasionally experience things like that, where performance isn't on par. In the case of CS2, the devs love Linux, so they will optimize for it in the future. It's just going to take a while.

Another example: I had to use Proton on a game that supposedly was native to Linux. Native implementations may sometimes suck; the good news though, is that you can easily use Proton, both inside and outside of steam. Seriously, I freaking love Valve for Proton, it's a fantastic tool.

This is all to say, that while gaming is absolutely possible nowadays, you will occasionally need add some flag, or familiarize yourself with proton, etc.

The exception, of course, being Kernel antichrists. Goddamn them. I can't play LoL anymore because of it. Well, I hate Riot so much now anyway, I'm not sure I'd want to anymore.

The nice thing about distro choice is that you don't really need to commit to one with them (mostly) being totally free. As long as you back up your files, I'd recommend trying a few until you feel comfortable. If you go with Ubuntu or Linux Mint I think you'll have the easiest time. I'd tentatively recommend dual-booting to give a new distro a try without fully committing, but that brings its own difficulties and troubleshooting with it. Having a second machine to test with is also great, but it's not a good option for everyone.

Can I mod games as freely and as easily as I do on Windows?

It depends a lot on the game, but in my experience not always. Running games straight from steam works really well with a small number of exceptions, but a lot of the sometimes weird tools for patching exe:s and so on that some games use can sometimes be a pain to get running. Not necessarily impossible but yeah this is a reason for why I still keep around my windows installation for dual booting.

I have used Windows all my life, and I have some questions

This is a great place to ask

But all I know about Linux is 1: it's a cantankerous beast that can smell your fear and lack of computer skills and 2: that's apparently not true any more?

Yes and no, the primary skill that you will be tested when using Linux is the ability to learn new things and adapt to changes. People misinterpret this as being complicated when in many cases its simpler but different.

I'm pretty much a fairly casual PC-user, I don't do much more than play games. So I wrote down some questions I had about Linux.Will my ability to play games be significantly affected compared to Windows?

Depends, if you mostly play single player games then most likley not. If you play online games than maybe not also maybe not.

Can I mod games as freely and as easily as I do on Windows?If a program has no Linux version, is it unusable, or are there workarounds?

Depends on the game, for something like Minecraft or Doom youll be fine but games with less support may not have good Linux support.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Yes, Wine has alternative frameworks and libraries

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

OS updates can either be done through the package manager or your distributions GUI software center

How does digital security work on Linux? Is it more vulnerable due to being open source?

On the surface it may seem so because more CVEs (Common Vulnerabilities and Exploits) are found on Linux but they're also patched faster than Windows and mostly before they find their way into the wild. In addition Linux is designed more securely such as, using repos (so software can be verified as legitimate), not allowing user mode software to run in kernel mode (so no anticheat), and having more eyes on the code.

Is there integrated antivirus software, or will I have to source that myself?

Not really and nobody uses it, it's like MacOS in that regard

Are GPU drivers reliable on Linux?Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

For the most part yes but keep in mind there are new drivers that arent ready to be used, as long as you stay on stable drivers you'll be fine. Also hardware damage will most likley only occur if you do heavy overclocking and. Ignore temps.

And also, what distro might be best for me? Pop_OS

But all I know about Linux is 1: it's a cantankerous beast that can smell your fear and lack of computer skills and 2: that's apparently not true any more?

It is indeed not true anymore. In the year 2025 Linux is easier to use than Windows, and even not too tech savvy 60-year-olds manage just fine. Though you should know 'Linux' is not an operating system. When saying 'Linux', people most often refer to it as a family of operating systems. Many of which are incredibly user friendly and ready out of the box. And many of which aren't.

Will my ability to play games be significantly affected compared to Windows?

Short answer: no.

Long answer: only for a handful of online games, e.g. League. If using Steam, there's virtually nothing you have to do. Epic and GOG are easy to use, but theough third party launchers. Other storefronts/launchers are harder to set up, but all of them work. It should be noted Steam is the only platform with official Linux support. Here is a database of Steam games with info on Linux and Steam Deck compatibility.

Can I mod games as freely and as easily as I do on Windows?

Depends on the game. Overall definitely not 'as freely and as easily' as on Windows. For Steam Workshop games, it works just as it does on Windows. For the rest sometimes you need to do a little work, sometimes a lot. Bethesda titles seem to be the most problematic on Linux when it comes to modding.

If a program has no Linux version, is it unusable, or are there workarounds?

Most of the time it is fairly straightforward and works nicely. Some are particularly difficult to get working on Linux, e.g. MS Office, so you might as well forget that.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Yes. There is software specifically for compatibility with Windows' libraries. While .NET framework you can simply install like you would on Windows. This is in fact needed in order to mod some games.

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

As mentioned at the start, Linux isn't a single OS, so it highly depends on the specific distribution (OS from the Linux family, in simple terms). Usually you just go to your app store and click on updates. Of course, there are other ways of updating the system and the choice is yours.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

Linux is extremely more secure than Windows. The whole 'open source leads to vulnerability' is a myth. There are antiviruses for Linux, but nobody uses them. There is barely any malware targetting Linux, and when you encounter it, most of the time you'll have to mess up and run it yourself giving it permissions. There are also more security-focused Linux distributions.

Are GPU drivers reliable on Linux?

Nvidia: not really.

AMD and Intel: yes, incredibly reliable.

For AMD and Intel you don't need any additional drivers, other than the generic drivers that come with the OS. They work perfectly and you can play games right away. For Nvidia you would have to go through the not-so-pleasant process of installing their drivers.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

No. This sounds like something somebody who's never used Linux would say on Reddit. While technically it is possible, just as it is possible on Windows, this is not something you will likely encounter at any point.

And also, what distro might be best for me?

Personally I'd go with Fedora. It's very easy to use. It looks nice too, kind of like MacOS. By default, that is, since you always have complete freedom to customize how your system looks. My gf, who doesn't know what a Shift key is, is able to use Fedora just fine. For both gaming and web browsing. This is how simple Linux has gotten in the last years.

Most people will probably recommend Linux Mint. Another great choice for beginners. The UI/UX is very similar to that of Windows. Personally it's not my favorite, but it's up to user preference. You definitely can't go wrong with it.

There is also Pop!_OS, which is similar to Fedora. However, it does include an ISO for systems with Nvidia GPUs, so you don't have to go through the trouble of installing the drivers.

I'd highly recommend trying one of these. If you like any of them, then just stick to it, and you'll have a great experience.

Will my ability to play games be significantly affected compared to Windows?

It depends on how often you play games with aggressive anti cheat, or games on non-steam platforms. Games like Valorant and Fortnite probably won't work at all. But I do a ton of non-competative multiplayer (and single player) gaming that is not inhibited at all.

Heroic launcher is your best bet for non-steam platforms (GoG, Epic, Amazon), and lutris/bottles should probably be your 3rd option (I've used both for battle.net). But steam games running through proton should "just work".

Can I mod games as freely and as easily as I do on Windows?

The actual modding should be arguably more accessible. You technically have control over the entire kernel, so nothing is going to stop you from doing whatever you want. The only problem you may run into is if you're dependent on modding tools that were only made for windows. Some of those tools are basically spyware anyway (ex. Curse), and often times the open source community has made its own alternative you should be using instead.

If a program has no Linux version, is it unusable, or are there workarounds?

YMMV. Valve has done a lot of heavy lifting to get proton to be a one-stop-shop for running windows games on Linux but you can add a program as a non-steam game, launch it through steam, and it often just works.

Wine is your other option. Sometimes the community has gotten windows apps running reliably in wine or proton, other times no one has ever tried it or it's too much of a headache to get working. protondb.com has user reports for how various games run.

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

The short version is yes. The long version is the same as the previous answer.

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

Most distros come with some form of package manager that works similarly to an app store on your phone (an app store is basically a package manager with purchases). Ideally, everything you want to run can be installed through the distro's package manager, and then you use the package manager to update everything. But sometimes the software doesn't exist in the package manager, and you have to download, run, update, and sometimes even build from source, your own programs. Those programs usually have a guide on the best way to run it on popular distros.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

It is actually more secure due to being open source. Source code can be audited by anyone rather than relying on "security by obscurity". There are antivirus programs, but I don't know much about them. Generally, don't run programs from shady sources, don't expose your machine to the open internet, and don't run everything as root and you should be fine.

Are GPU drivers reliable on Linux?

Yes, though historically AMD has better support for the newer features asked for by Linux compositors (namely Wayland). Nvidia's drivers are still not fully open source, but otherwise work fine. Driver bugs are rare in my experience.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

To the same extent that windows can, yes. But if your concern is YOU misconfiguring something to cause Linux to do that, you shouldn't have to worry about it. It is unlikely you will be interfacing directly with the kernel at all. Most distros configure the kernel in some specific way they want and you never worry about it. And still, a proper kernel-level driver should ensure that it will never send commands that could damage something, even if the config vars are incorrect.

And also, what distro might be best for me?

First off, install Ventoy to a USB drive. Then take advantage of Linux's ability to "live boot" by downloading several .iso's for several different distros onto the USB. Then boot off the USB, and you should be presented with a handy menu of ISOs to pick from. This will make trying out a bunch of different options really easy, without actually installing anything to your hard drive.

I'd say try grabbing mint, fedora, Pop!Os, and opensuse to start. Maybe also try Zorin. These are all geared toward new Linux users.

Will my ability to play games be significantly affected compared to Windows?

No. Thanks to Steam Deck, most popular windows games also work on Linux. See https://www.protondb.com/ for a complete list of 18,000 titles.. Someone already mentioned that kernel level anti-cheat is the big, obvious blocker.

Can I mod games as freely and as easily as I do on Windows?

~~Im guessing that most moders target Windows users therefore, don't think mods would be AS easy. Not saying modding wouldn't exist or work at all.~~ Edit: see sp3ctr4l's reply to this comment. They know more than me

If a program has no Linux version, is it unusable, or are there workarounds?

There are workarounds. Linux has some great alternative software to popular paid stuff. See LibreOffice or Krita.

There are also more advanced options to run Windows apps under Linux, see Wine or Virtual Machines

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

Yes. Similar to the above answer/ similar to aforementioned Proton. For .NET specifically, there is a Linux runtime.

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

This can depend a lot on what distribution you're running, but definitely, there are ones with easy buttons for whole-system updates.

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

It's different and probably overall better than windows. Most distros are much better out of the box than windows.

Open source is ususually a security advantage because (long story short) security mistakes can be caught by more people.

I don't have a good answer for you on anti virus. I am very privacy and security conscious and I dont use one on linux. My personal opinion is that you don't need one and shouldn't need one if you're not downloading sketch stuff.

Are GPU drivers reliable on Linux?

Totally. GPU drivers are much, much better than they used to be.

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

Theoretically. You would have to try really hard, but for normal use, no. More likely, you could lose data or access to the system if you misconfigure stuff (just like with Windows)

Distro recommendations. My personal opinions, don't flame me.

• Bazzite. hard to mess up, gamer focused, super simple updates, and targeted support for gamer hardware. Feels like a cross between steam deck and windows. Less support for tinkering but if you never want to touch the terminal, this is my choice.

• Pop!OS. Simplified Linux with great driver and steam support with easy updates. More tinkering support than Bazzite

• Linux Mint. Easy to start on but more traditional back-end. Much more support (forum posts) than the previous two. A lot of what works on Debian or Ubuntu works the same on Mint, so you'll be able to do all kinds of fiddling

On the gaming side, it depends a lot what games you play. Generally the rule is (at least for single player) that it will work through Proton or a native version, unless otherwise specified. Personally, pretty much all of my Steam library works perfectly on Linux, even some games on launch day (Persona 3 Reload was flawless day 1). For modding your mileage may vary but if the game runs there's a very high chance the associated modding tool will work too, although it might require some more tweaking than you are used to in order to get it to work properly as quite a few tools will assume you are running Windows. Multi player games are where there can be some trouble - for example Fortnite is a notorious example of a game that refuses to run on Linux because Epic Games does not allow its anti cheat to work on Linux. ProtonDB and a good old fashioned go on your favourite search engine should be able to tell you if what you play works, doesn't work, or needs tweaks to get working.

Running non-Linux apps is a mixed bag. Some things (most notably games through Proton) can work through compatibility layers perfectly fine, even if they need you to install .NET or some other dependencies. Others will be totally unusable, at least for now. Make sure you check all the applications you need to work on a regular basis work before jumping in, so search up their compatibility with tools like WINE (translation layer to let Windows apps run on Linux, also what Proton is based on).

For updates, you'll love it far more than Windows. Since almost every app you could ever need is installed through either a package manager or Flatpak (closest analogy I can give is like a phone app store, but allowing you to install pretty much anything, including system stuff), your updates will all come in one place. For example, on my Fedora KDE install, all I need to do for updates is go into the Discover app (KDE's package management software) and into its update section, download, and install. This not only updates system software (desktop, kernel, drivers, so on) but also your applications. This means updating your system and apps is a breeze that'll take far less time than the usual pain that is Windows Update.

For security, you'll have a lot less to worry about than Windows, and I have to admit part of it is because Linux has a fairly small user base. Few malware writers are going to care about a few Linux desktops compared to plenty of unpatched Windows systems out in the wild. However, the open source aspect also helps a lot - rather than showing vulnerabilities to hackers, it's been valuable more to show these vulnerabilities to people who can fix them since the software is on public display. There's more eyes on the code, and more people who can fix problems before they become major vulnerabilities. For most regular desktop users, you will not need any antivirus. If you're really worried about viruses, I have heard ClamAV can scan for some things, but I haven't tried it myself as it really isn't necessary for desktop use.

GPU drivers can be a bit complicated. AMD and Intel are incredibly simple, since (at least for anything made within the last 10 or 15 years, if not older) the drivers are built right in and need zero configuration (it just works!). NVIDIA cards can be a bit more of a challenge. On a lot of distros, you can install the NVIDIA drivers usually during or right after install fairly easily, but they will be separate from the rest of the built in drivers. You can have a good experience with NVIDIA on Linux, but just expect there to be anywhere from a bit to a lot more effort needed to get some things working compared to AMD and Intel GPUs due to this separation. Of course, this will depend on your exact set up.

There's no real risk of damaging your hardware installing Linux, the only real danger is deleting files already on your main boot drive during installation, so make sure to double check your installer to see if it's doing what you want it to. Make sure you have a back up of your important stuff too, just in case. The only thing I can think of maybe is extreme overclocking through LACT or something maybe causing damage, but that's part of what you sign up for with overclocking even on Windows anyway.

Distros are a very debated topic, and there's no real "best" one, just one that fits your needs. If you're new to Linux, my personal recommendation is to go with something boring and well supported like some variant of Fedora or Ubuntu. There will be plenty of documentation for both to help you with things, and they both are fairly solid distros with good track records. However, one thing to keep in mind is what kind of desktop you want. Linux has multiple desktop environments (DEs) that can provide differing experiences (different way of launching applications, arranging icons, file managers, that sort of thing). If you're used to Windows, KDE definitely has the smallest learning curve, as a lot of things will be as you are used to, so it may be best to go for either the KDE variant of Fedora or Kubuntu. The main difference between Fedora and Ubuntu you will notice is that Fedora has a far faster update cycle, which means you get new features quicker, but you will have to restart for updates more often. In addition, I have heard that the NVIDIA drivers can be easier to handle on Ubuntu, so if you have an NVIDIA card it might be more optimal to go for an Ubuntu variant.
