Microsoft revealed that its DirectSR (Direct Super Resolution) API, which seeks to standardize super resolution-based performance enhancement technologies in games, is essentially based on AMD FSR 2.2, a Microsoft Dev Manager speaking at GDC has revealed. AMD has opened the code of FSR 2.2 on GPUOpen, which gives the technology greater visibility across the game developer space. This, coupled with the fact that FSR is entirely shader-based, and doesn't use exotic technologies such as AI, may have driven Microsoft use FSR 2.2 as the base for DirectSR. Any GPU capable of Shader Model 6.2 is capable of running FSR 2.2, and by extension, run DirectSR. The DirectSR standardized upscaling API should be as easy to implement for game developers, as AMD FSR, as the AMD upscaler works on fewer input parameters than the competing DLSS technology.
