Replace any 32-bit FSR2 DLL with the correct ffx_fsr2_vk.x64.dll from the official AMD FidelityFX SDK (version 2.2 or later). Ensure the Visual C++ 2019/2022 x64 runtime is installed. ffx fsr2 api vk x64dll work
: Many users search for this DLL when trying to "inject" FSR 2 into games that don't officially support it (e.g., swapping DLSS for FSR 2). : The interface that allows the game engine
