Get more than 2x FPS in games with this one simple trick!

[Lopyt]

So there is a technique where a 3D renderer can generate fake frames at a low cost to give the illusion of higher framerate, by using parallax and the depth buffer for each pixel of the screen to kind of warp the view while the computer is generating a new real frame. This tends to generate black blobs where objects occlude each other, however, which is an awfully ugly artifact. You may be able to use some kind of motion blurring algorithm or AI reconstruction to make that area look more natural, or limit this parallax to motion that do not change the occlusion of objects. The black blobs that happen at the edges of the screen can be stretched too to compensate since information that far out is likely not very visually noticable most of the time. 


Since every 3D game has a depth buffer, is there a way to write an app that applies this technique to any game as a post processing effect for more smoothness and less stutter?

Are the cool dudes on OS good enough to make such an app? Information on this concept is difficult to find


Something similar is used often in VR games but I dont see much in not-vr stuff
