Using FSR 1.0 in 2024 when FSR 3 already exists is cringe.

There is a way around it, but its quite annoying. By using DLSS unlocker into tricking the game that DLSS is available on AMD which then forwards the API calls to FSR 2 or XeSS. This works for a lot of games, but who knows if it would for FFXIV. This is because DLSS dll has IsSupported call game engines check, but its possible some games detect nVidia/AMD directly.

Generally this way sharpening is not used so need reshade filter to add it back.
