Describe the bug When trying out VR once again on linux using the Valve Index, I've noticed that this issue is still going on; whether I use Steam(Runtime), Steam(Native), SteamVR(beta), SteamVR(stable), SteamVR(Older build for linux users), my HMD's response time is way to high, making the view in the hmd lag behind where my actual gaze should be, creating this dizzying effect in the headset that strains the eyes. I've also noticed that frame times are way higher than what I had on windows, especially when not in steamvr home or any vr apps (on windows = >1 or 1ms at 90hz, on arch linux <3ms at 90hz).

To Reproduce Steps to reproduce the behavior:

  1. Run Arch linux with the latest LTS linux kernal
  2. Use Steam Runtime (or native)
  3. Run SteamVR (beta, stable, or older linux build)
  4. Long response time view.

Expected behavior From the experience I had on Windows 10 and 11, I expected my view to have a 1 to >1 ms response time.

System Information (please complete the following information):

  • Distribution: [Arch/Manjaro/Ubuntu/etc.] Arch (LTS Kernel)
  • SteamVR version: 1.23.7 & linux_v1.14
  • Steam client version: Aug 31 2022, at 04:28:42
  • Opted into Steam client beta?: [Yes/No] Yes
  • Graphics driver version: [run nvidia-settings or vulkaninfo | grep driverInfo: Mesa 22.1.7
  • Gist for SteamVR System Information: System Report

Performance Data (optional, but very helpful):

  • CPU: AMD Ryzen™ 9 5900X × 24
  • GPU: AMD Radeon™ RX 6800 XT
  • Gist for perf top: n/a
  • Link to gpuvis trace: n/a

Could not perform the last two instructions due to SteamVR(beta), SteamVR(Stable), and SteamVR(Linux_v1.14) not providing the options described in the instruction set.
