Been trying to get Steam VR to work with an Oculus 2 for a while now, but with no luck. So far, nothing I have found on forums has helped. Thought I would post here and see if maybe someone might have some insight. I am able to connect, but I always get the below graphics issue. I have swapped around frame rate, refresh rate, and other misc graphics settings but no luck.

PC: Framework 16 (Ryzen 9 7940HS)
Graphics card: AMD Radeon RX 7900 XTX
OS: Bazzite 43
VR Headset: Oculus 2

Hello @merlin3of5, we've seen this kind of corruption before if vrcompositor ends up on a different GPU from Steam. Can you check which GPU is being used for those with a tool like amdgpu_top?

I believe I am using the 7900 xtx. Attached is a screenshot of amdgpu_top. I have also set "DRI_PRIME=1 %command%" as a launch option for SteamVR(And all games)

@merlin3of5 -- Are you on the current beta, or the public release? If you're on the public release, could you swap to the beta branch and try it with 2.16.3?

Since this is with vrlink specifically, which was not handling GPU selection properly for the compute shaders in multi-GPU cases, I think this is addressed by a fix already in the beta builds.

I have tried swapping between public and beta a few times(including version 2.16.3), but no change.

Well, drat. So much for that theory.

Could you bundle up some of the logfiles? In particular driver_vrlink.txt and vrcompositor.txt, though vrserver.txt would also be helpful. All should be in ~/.steam/steam/logs/ by default.

For the sake of testing, can you check that Steam is also launching on that GPU?

@Packetdancer, you are awesome. Did not realize I needed to (or even could) set Steam itself to launch on the dedicated GPU.

For those who end up here, all of my games are set to use the dedicated GPU using launch option "DRI_PRIME=1 %command%" but Steam itself was using the onboard graphics. Enabling "Run using dedicated Graphics card" fixed the issue.
