The most popular social VR game, here are resources to get the best experience on Linux.
## Recommendations
Proton version: [Proton-GE-RTSP](https://github.com/SpookySkeletons/proton-ge-rtsp/releases) - this will give you the most painless experience.
### Performance Tuning
In VRC, it's very easy to hit a CPU bottleneck. Avatar material count, avatar mesh count, pixel light count, phys bones, particles all contribute to CPU load.
How to check if you're bottlenecked by CPU or GPU:
- Check GPU usage in `nvtop` (any GPU) or `nvidia-smi` (NVidia-only).
- If it's not at 100%, you're likely CPU bottlenecked.
- SteamVR: Lower the SteamVR render resolution.
- If your FPS doesn't increase, you're likely CPU bottlenecked.
What to do if CPU bottlenecked:
- Reduce Maximum Shown Avatars
- I recommend 10-15 as a base setting, likely won't be interacting with more people than that at the same time.
- Block Poorly Optimized Avatars: Very Poor
- Can still show-avatar people who you are actively interacting with.
- Will often notice that showing a speficic person's avatar will wreck your performance, while everyone else's avatars are fine. Blocking very poor by default makes you more aware on whose avatar has a large impact.
- Optimize your avatar, and nag your friends to do the same.
- There are many tools that let you do this in a few clicks, even if you are completely clueless about what to do.

In-game settings:
- Graphics:
- Anti-Aliasing: Off or 2x
- Greatly increases GPU load (even more so on NVidia)
- Try with off first, if the jagged edges bother you too much, try 2x.
- Pixel light count: Low
- Each pixel light adds significant CPU load.
- Turning these completely off will make some worlds look incorrect (too dark).
- Shadow Quality: Low
- Adds significant GPU load.
## Common issues
If you utilize pipewire [this workaround is required not to drop audio from time to time](https://wiki.archlinux.org/title/PipeWire#Audio_cutting_out_when_multiple_streams_start_playing) on displayport audio headsets like the valve index.
{{< hint info >}}
Disable your antialiasing entirely in the game graphical settings, this appears to carry a significant performance penalty on both AMD and moreso Nvidia. Do not use the in game antialiasing.

(Controversial; same issue also encountered on other servers.)
When hosting a lobby west servers should always be utilized instead of east servers as the infrastructure is significantly more reliable.
