Operating Systems

There are definitely a few games you sacrifice going Linux-only still, mostly to anticheat support. That said, my productivity has absolutely tanked in the last couple years so you can certainly find games to play. Being a patient gamer has great synergy because by the time you get around to playing something whatever kinks there may have been are usually worked out.

I have looked into this myself recently. Still a few blockers for me, one of the big ones being VR. The Steam Deck and its OS have really pushed gaming forward on Linux though.

I'm in the same case, I really tried using Linux as my primary OS but I always go back to Windows for some games.

Honestly I don't think that local Gamepass will come to Linux ever.

For other games it will work mostly, except some multiplayer games that use anti cheat, some games will work with anti cheat but it's on a per game basis, so it depends which multiplayer game you want to play.

Gaming on Linux has grown leaps and bounds and it's only getting better. Game Pass Ultimate though, I'm guessing you're gonna have a rough time. That's built for Window's ecosystem. So more than likely that's going to be a very sore point. The streaming Game Pass can and does work on Linux, but if you're against that then Linux might not be for you.

Steam has gotten to the point on Linux where it's basically just install and run, as long as you have compatibility for all games turned on. Very very very few games haven't worked for me or even require little tinkering anymore. That being say I pretty much really only play Indie games.

It's possible to get gamepass and steam (and epic and ubisoft and itch.io) to both integrate with Playnite launcher.

This would still require you be able to run the xbox launcher, but it makes Playnite the interface you use and the other launchers are just opened in the background mostly, except for updates.

Anyway Playnite is a very customizable and lightweight open source launcher and maybe you might like it even though it doesn't actually solve the problem you're talking about here.

Edit: Playnite works on both windows and linux.
