Asynchronous Reprojection (improve playability at low FPS)
CodeF53 opened this issue ยท 2 comments
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:

Implementation in vulkan
Just here to note someone made a PoC of this in minecraft

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