Maybe I don't get it, but occulus and valve solved this problem for VR back in 2015/6, surely if it worked to bring up frame rates for VR to stop everyone vomiting similar techniques would have been suitable in normal 3D games? But it's now 2024 and frame generation is only just becoming a thing? Like is said I'm not massively up on the technicality side of things, just seems that it's something that seems forgotten outside of custom solutions by individual developers
