Dynamic Foveated Rendering (DFR) support would be a huge performance win for VRChat now that eye tracking is becoming mainstream in VR. Many current headsets already support eye tracking (e.g., Bigscreen Beyond with eye tracking, several Pimax models, Quest Pro), and upgrade kits for older headsets like Valve Index are also starting to appear.

There’s an older 2023 request, but it’s outdated given today’s headset landscape, so I’m opening a fresh one:
