VRChat just recently(around friday) added a new beta to the steam version: it now uses Unity 6!
I personally tested it and performance seemed a bit better, but some friends with slower PCs have reported 2x FPS improvement(one went from 20fps average on a world with ~15 people to 40fps)
So far the biggest concern, shaders not working due to changes in the render pipeline, didn’t seem to happen at all! Neither me nor any of my friends came across issues!
Finally vrc, after years, is updating the unity version!
To get it go to your Steam Library -> Right Click VRChat -> Properties -> Game Versions and Betas and there select “unity-6“
