I would love to see this thread receive more votes! From what I understand, if a game already has FidelityFX CAS implemented as part of the game engine, then adding FidelityFX Super Resolution is a matter of slotting in code for FSR into the existing FidelityFX CAS framework (yes, this is an over-simplified explanation, pump the brakes).
Hopefully we can get more visibility on FidelityFX Super Resolution, since it will work with both AMD and Nvidia GPU’s, and may be much easier to implement than Nvidia’s DLSS, but will benefit owners of both brands!
