Lag spikes in SteamVR with nvidia-open caused by GSP firmware to finally be fixed in future driver releases (forums.developer.nvidia.com)

Seeing this makes me really happy. The nvidia-open drivers run VR as smooth as with Windows, but these lag spikes ruined the experience.

hopefully this ends up helping the desktop experience as well. I've been disabling the GSP for the nvidia driver because it seems to introduce weird stutter to my desktop (kde/plasma). And switching to nvidia-open just has the stutter all the time (because can't disable the GSP).

On that note, what is the gsp even for?

Interesting. Are you on Wayland? It supposedly is to offload GPU tasks from the CPU to the GPU.

"Some GPUs include a GPU System Processor (GSP) which can be used to offload GPU initialization and management tasks." https://download.nvidia.com/XFree86/Linux-x86_64/510.39.01/README/gsp.html
