FSR on actual PS3 hardware?

FSR 1 is a purely spatial technique, so you can apply it to a video output, it's technically possible if you capture your PS3's video output and apply the FSR 1.0.2 pass.

A quick way of doing this that I can think of right now is to play your capture card's output in real time though mpv while using a config that has FSR upscaling such as https://gist.github.com/agyild/82219c545...65ce0b0ce5.
