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

Microsoft has outlined a new Windows API designed to offer a seamless way for game developers to integrate super resolution AI-upscaling features from Nvidia, AMD, and Intel. In a new blog post, program manager Joshua Tucker describes Microsoft’s new DirectSR API as the “missing link” between games and super resolution technologies, and says it should provide “a smoother, more efficient experience that scales across hardware.”

“This API enables multi-vendor SR [super resolution] through a common set of inputs and outputs, allowing a single code path to activate a variety of solutions including Nvidia DLSS Super Resolution, AMD FidelityFX Super Resolution, and Intel XeSS,” the post reads. The pitch seems to be that developers will be able to support this DirectSR API, rather than having to write code for each and every upscaling technology.

The blog post comes a couple of weeks after an “Automatic Super Resolution” feature was spotted in a test version of Windows 11, which promised to “use AI to make supported games play more smoothly with enhanced details.” Now, it seems the feature will plug into existing super resolution technologies like DLSS, FSR, and XeSS rather than offering a Windows-level alternative. 

Microsoft says that the new API will be available soon via a preview version of its Agility SDK. It plans to offer a “sneak peek” of how DirectSR can be used during a developer session at the forthcoming Game Developers Conference (GDC). The session will take place on March 21st, and will include representatives from both Microsoft as well as Nvidia and AMD.
