Asynchronous Reprojection (improve playability at low FPS) #290

Open CodeF53 opened 10 months ago

Virtual Reality has been using asynchronous reprojection to increase perceived framerate and responsiveness for nearly 4 years.

The effect works by translating/rotating (simple matrix multiplication) the last rendered frame and projecting it to give better feedback for camera movement before a new frame is rendered.

Demos of the idea:

The performance is awful tho, and implementation isn't perfect. But yeah, it works, and even compatible with Sodium
