fsr4

OptiScaler bridges upscaling/frame gen across GPUs. Supports DLSS2+/XeSS/FSR2+ inputs, replaces native upscalers, enables FSR-FG/XeFG on non-FG titles. Supports Nukem mod for DLSSG-to-FSR3 FG.

Faster FSR 4.1.2 upscaling on Radeon RX 6000 and RX 7000 graphics cards, on Windows and Linux: drop-in DLLs and shader overrides. Exact version keeps AMD's picture byte for byte; optional lossy version is faster still.
