i would say first have the game use more cpu cores properly.
wow already has it its under advance tab resample quality.
Correct, but i believe that’s FSR 1.0, AMD released 2.0. Just a matter of the game implementing it. Which AMD says should be quick and easy, not sure how that works for the developers.
you can already us it in wow now but there is no point unless you want to use ray tracing with it.
