What Is Reprojection in Vr?

Asynchronous reprojection is a class of motion interpolation techniques aimed ensuring a virtual reality headset's responsiveness to user motion even when the GPU isn't able to keep up with the headset's target framerate, and to reduce perceived input lag at all times regardless of framerate.

What is VR motion reprojection?

When motion reprojection is enabled, all Steam VR games will render nominally at ½ frame rate (45 fps instead of 90 FPS) while Windows Mixed Reality for SteamVR uses motion vectors generated by the GPU to extrapolate the next frame.

What is reprojection in VR Reddit?

Reprojection is when a VR game can't hit the full 90 FPS supported by the headset, so it instead runs at a fraction of that and smooths the in-betweens to simulate full 90fps (it's not as good as native 90fps, but it's better than just running at a low framerate for most people).
