So the article above is sraight up wrong? All frame generation is already extrapolation, not interpolation?
I had to look it up because I could have sworn that reprojection can and does use motion vectors to do more than just update the perspective.
AND IT DOES.
You’re talking about what VR does as the last step of EVERY rendered frame, which is an extremely simple reprojection to get the frame closer to what it would have been (what oculus called ATW), had it been rendered instantly (which it obviously can’t be). This is also seemingly the extend to which the unity demo showcased by LTT took it.
What Oculus called ASW, asynchronous space warp, absolutely can and does update the position of the ball, which is why it can and is used to entirely replace rendering every other frame.
Valves version of it is a lot simpler, and closer to just ATW, and does not use motion vectors when compensating for lost frames. Unlike ASW their solution was never meant to be used constantly, for every other frame, to enable VR on lesser hardware.
