Microsoft is working with Nvidia, AMD, and Intel to improve upscaling support in PC games

Microsoft has outlined a new Windows API called DirectSR designed to integrate super resolution AI-upscaling features from Nvidia, AMD, and Intel into PC games. DirectSR is described as the "missing link" between games and super resolution technologies that will provide a smoother, more efficient experience scaling across hardware. The API enables multi-vendor super resolution (SR) support through common inputs and outputs, allowing a single code path to activate technologies like Nvidia's DLSS, AMD's FidelityFX Super Resolution, and Intel's XeSS. Developers will be able to support this DirectSR API rather than writing code for each individual upscaling technology. The announcement comes after an Automatic Super Resolution feature was spotted in a Windows 11 test build that promised to use AI to enhance game details and smoothness. It seems this feature will now plug into existing SR technologies like DLSS, FSR and XeSS rather than offer a Windows-level alternative. The new DirectSR API will be available soon via a preview of Microsoft's Agility SDK. Microsoft plans a GDC session on March 21st to provide a sneak peek of how DirectSR can be used. The GDC session will include representatives from Microsoft as well as Nvidia and AMD. The goal is to make super resolution technologies easier for developers to integrate and support across different hardware vendors.
