Microsoft wants to unify DLSS, FSR and XeSS upscaling technologies with DirectSR

Microsoft recently unveiled a new API called DirectSR for Windows that lets game developers include support for multiple super resolution technologies using a single piece of code.

Microsoft recently announced DirectSR, a new API for Windows that will enable developers to write a single piece of code for popular AI super-resolution AI upscaling technologies like DLSS, FSR and XeSS. Developed in partnership with AMD, Intel and Nvidia, the tech giant says DirectSR is the “missing link” between games and various super-resolution techniques.

Right now, game developers have to write code for every upscaling technique, which makes it difficult to include support for different upscaling methods. The company said the new API enables “multi-vendor SR through a common set of inputs and outputs”, meaning developers will be able to use AMD FidelityFX Super Resolution, Intel XeSS and Nvidia DLSS Super Resolution without having to add support for every one of them.

This will in turn give more gamers options to choose from. For example, if a PC game supports multiple upscaling methods, gamers will be able to choose if they want to use DLSS, FSR or XeSS depending on their graphic vendor. It will also give a significant performance boost for gamers without compromising on image quality, especially for those who don’t have top-of-the-line graphic cards.

The blog post also states that a public preview for DirectSR on Windows will soon be available in the Agility SDK and that the API will be compatible with both Windows 10 and Windows 11.

While Microsoft has yet to share details about DirectSR, the upscaling method might work on recently launched graphic cards, the company said it will give a glimpse of DirectSR at the upcoming Game Developers Conference (GDC).

A few weeks ago, Microsoft was testing a new feature on Windows 11 called ‘Automatic Super Resolution’ which the company said used “AI to make supported games play more smoothly with enhanced details”. But now it looks like instead of working on a new super-resolution technology, the tech giant seemingly wants to tap into existing upscaling techniques.
