Quote:Microsoft DirectSR is an DirectX API for super resolution that will support DLSS, FSR and XeSS

Microsoft is slowly lifting the lid on the upcoming Super Resolution feature for DirectX. 



Perhaps to avoid further confusion before the grand reveal of DirectSR, Microsoft has made clear in a new blog post that DirectSR is not a new super resolution technology. This is an API for game developers that will streamline integration of existing and future super resolution technologies seamlessly.

The DirectSR was developed with the help of major GPU vendors like NVIDIA and AMD, who will also be presenting the technology in March at GDC 2024. It looks like these companies have found the common ground on what is actually required for temporal upscaling to work in games. In most cases that involve motion vectors, depth and color buffers, reaction marks and exposure. Those variables (in case of FSR) have to be shared between frames for upscaling to work efficiently. It is assumed that other temporal technologies have similar requirements, and DIrectSR could potentially add more variable for future upscaling techniques.
