Yes, it's ancient, but at the very least I'm curious why it doesn't work. I'd say it's a fair usecase, since Dx11 is supported on my system and the gpu is only just a bit too slow to play GTA V comfortably at any resolution that looks decent on a FHD (or 1200p) display. FSR on systems like mine would be a godsend!

EDIT: Just to make sure I've confirmed FSR 1 can work on older hardware such as mine. FSR turns out to be working fine on Edge of Eternity.
