: The game launcher failed to install the redistributable or a mod removed it.
The ffx_fsr2_api_vk_x64.dll acts as a bridge between a game's engine and the FSR 2 SDK.
Unlike a standard .dll that simply exports functions, this DLL implements the interface. When a developer integrates FSR2 into a Vulkan game, they do not write the upscaling math themselves. They call standard functions like ffxFsr2ContextCreate and ffxFsr2ContextDispatch .
