Hello @trashhead101, this reads like https://github.com/ValveSoftware/SteamVR-for-Linux/issues/631#issuecomment-2209439380 and following comments. Can you test how SteamVR behaves with GSP disabled or with the NVIDIA 550 series driver?
well, the problem started with NVIDIA 555 driver, but rolling back driver would be to much trouble for me. Can you provide me a way to disable GSP?
I don't have a better testing suggestion than https://github.com/ValveSoftware/SteamVR-for-Linux/issues/631#issuecomment-2216836976.
Ah, I got it. It works with disabled GSP:
Here the way to do it:
go to /etc/modprobe.d/ (cd /etc/modprobe.d/)
create a file called nvidia.conf (sudo nano nvidia.conf)
and then write options nvidia NVreg_EnableGpuFirmware=0
now on: [Rebuilding the initial ramdisk]

Thanks @kisak-valve and @trashhead101 , that did in fact solve my problems!

Describe the bug
After using the newest NVIDIA 555 driver (KDE Plasma), SteamVR is subject to immense stutter.
The stutter is strongly only visible when moving your head with the headset on (Looks like a frame from a few milliseconds ago is rendered on the headset).
The lag is visible in the little SteamVR window, with the display performance graph enabled, via tons of pink markers.
(
Weirdly the strength of the stutter changes (in the SteamVR home) after what king of window is open / coveres the desktop, where the files are displayed. For example a browser with excactly reddit open reduces/deminished the stutter nearly completely, while the stutter is only slightly lowered by having a browser without a website or a website like Youtube open. You can check the pictures attached to see this.
In a real game, no matter what windows are opened, there is constant stutter and it is basically not playable.
