AMD FSR 4.0 and AFMF 2.1 Leaks Emerge from Driver Performance and Hardware Implications

Leaked AMD Driver Hints at FSR 4.0 and AFMF 2.1 The internet is abuzz with a reportedly leaked AMD Adrenalin driver from late December 2024. This early driver build, spotted by tech enthusiasts like @GawroskiT, could offer an early look at future graphics tech from AMD. The focus is specifically on FidelityFX Super Resolution and Fluid Motion Frames. FSR 4.0 in Plain Sight The most interesting discovery is a large DLL within the driver package. This 17MB DLL appears to contain the implementation for FSR 4.0. In comparison, the current FSR 3.1 DLL is about 6.5MB. This size increase may indicate significant rewriting or added functionality in the upcoming FSR version. Furthermore, the DLL also contains code for FSR 3.1. It includes what seems to be a mechanism for the driver to swap in the active FSR implementation used by games dynamically. This level of driver-side control could be a game changer for handling upscaling technologies in the future. FP8 and the Hardware Implications Delving in…
