Microsoft's DirectSR aims to unify PC gaming upscaling

If you play PC games today, you already know the drill: Nvidia has DLSS, AMD pushes FSR, and Intel offers XeSS. They all make games run faster, but supporting all three has been a recurring headache for developers.

Now, Microsoft is stepping in to untangle the mess. The company just unveiled DirectSR, a new Windows API developed alongside Nvidia, AMD, and Intel to streamline AI upscaling across PC games.

One code path to rule them all

In a recent blog post, Microsoft program manager Joshua Tucker called DirectSR the missing link between modern games and super resolution technologies.

Instead of forcing studios to implement bespoke code for every vendor, DirectSR standardizes inputs and outputs. Developers write to a single code path, which can then tap into Nvidia DLSS Super Resolution, AMD FidelityFX Super Resolution, or Intel XeSS.

This also explains the mysterious Automatic Super Resolution toggle recently spotted in test builds of Windows 11. Rather than building a native, proprietary Windows upscaler from scratch, Microsoft is simply plugging its OS into the existing graphics tech stack.

Developers will get their hands on DirectSR soon through a preview version of Microsoft’s Agility SDK. Microsoft also plans to showcase the feature on March 21st during the Game Developers Conference (GDC), joined on stage by representatives from Nvidia and AMD.

Why it matters

We think Microsoft’s approach here is very smart, prioritizing ecosystem cohesion over proprietary ego.

For game studios—especially indie and mid-tier teams with limited engineering bandwidth—supporting upscaling just became vastly cheaper. Until now, smaller games often implemented DLSS and skipped the rest. DirectSR makes multi-vendor support essentially automatic, meaning players on AMD and Intel hardware will encounter far fewer games where their native upscalers are missing.

For the industry, this marks the transition of super resolution from a fragmented hardware turf war into standard PC infrastructure. Microsoft is leveraging Windows to do what it does best: create a unified abstraction layer across competing silicon.

That said, there is an obvious potential bottleneck. Upscaling tech moves fast, with vendors constantly branching out into frame generation and ray reconstruction. A lowest-common-denominator API risks lagging behind proprietary advances. Still, making baseline super resolution universal across PC gaming is a massive win for players.
