 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.
