Steam vr performance

SteamVR performance on linux is particularly choppy.

Tutorials

run w/o SteamVR GUI

General

- Within steamVR settings, decreasing framerate to 120Hz helps a lot
- Within steamVR's per-application video setttings, advanced, decreasing resolution helps

Linux

General

- Disable X11 compositors like `xcompmgr` to improve performance
- 3x individual 1080p displays rather than one large TwinView screen helps performance slightly
- Apparently, running game without steamvrUI is a massive performance booster

Nvidia-Specific

Disable Async Reprojection

Apparently, this has a huge impact when using nvidia drivers.

// ~/.steam/steam/config/steamvr.vrsettings

{
   "steamvr" : {
      "enableLinuxVulkanAsync" : false
   }
}
