Reducing FOV for performance, +40-100% fps, playable at 36fps without scaling with mid end card and quest 2 via link, does not really reduce FOV on device

I did another post explaining what i now think it’s happening here based on this thread

Removing "unused FOV" - free fps?

[image] (You can corroborate this yourself by peeking under your HMD into the desktop screen) Not an expert in VR at all, but it seems like the scene that the app renders is around 50% wider and taller than what we see on our HMD screens, this makes sense to some extent as VR relies on reprojection and the device will keep the 90hz while rotating your head by projecting the scene provided by the app, so this extra buffer can help the HMD project on rotation. I think sudden movements are rare…
