Somewhat related, Meta recently introduced SysPTW which is basically frame generation for the Quest:

> We’re introducing System Positional TimeWarp (SysPTW) from Depth-From-Stereo to Quest headsets. PTW uses real-time scene depth to reduce visual judder and lag when apps drop frames, making movement in VR smoother and more comfortable. [...] You can expect a more stable experience, especially in demanding social and gaming apps.

The "demanding social apps" they aren't naming here is almost certainly VRChat which is poorly optimized on the Quest.
