Microsoft on Wednesday made the DirectSR API Preview available to game developers through the DirectX GitHub. The API aims to simplify implementation of super-resolution technologies with games. A super-resolution technology renders your game at a lower resolution that your display resolution, and upscales it to your display resolution using intelligent upscalers that attempt to reconstruct details lost to the process. This yields a significant gain in performance from the lower render resolution, and lets you max out game settings—something you could only do if your hardware was up to it. By default, DirectSR provides an upscaling technology based on AMD FSR 2.2, but the API looks for the best available technology available with the graphics drivers that are supported by the game. All three discrete GPU makers responded positively to DirectSR.
