Symptoms

When playing the game in VR mode looking around with your head causes stuttering. Moving forward and back with the stick is smooth. Panning left / right with the joystick seems smoother then looking with head but still has some stutter.

Reproduction

I am using a Pico4 connected to my PC using the ALVR streamer app (v20.14.1). Other games work flawlessly without issues. Examples beat saber, VRChat, Fallout 4 VR, Half-Life Alyx. I have also tried the game on windows using ALVR streamer and it has no stuttering issues on windows. So I am pretty sure this comes down to a proton compatibility issue.

When running the game my GPU is only utilizing about 80% so it has headroom. So it's not stuttering because of constrained resources. Also the game runs smooth if I play in Desktop mode on Linux. I also tried turning the graphics down to low setting and setting the render resolution to 50% just to make sure I have lots of headroom but the stuttering continues. Again works flawless on windows same computer so really don't think it's a low resource issue.

Please let me know if you need any other testing done. Thanks!
