AMD, Microsoft, and Nvidia are getting cosy at GDC 2024 to tell us all about the new DirectSR upscaler

PC gaming's (un)holy trinity of hardware and software vendors will be taking the stage at this year's Game Developers Conference (GCD) to provide more details on what's new in the world of graphics. Work graphics, a DirectX 12 feature that first appeared in beta form last year, will take the lion's share of the presentation but alongside it will be a preview of DirectSR: Microsoft's new system for implementing upscaling on devices running Windows.

One of the sessions in this year's Game Developer Conference will be all the latest DirectX graphics technologies being developed by Microsoft, with input from AMD, Intel, Nvidia, and Qualcomm. The first of which is DirectSR, aka Direct Super Resolution. At this moment in time, we know very little about what this is, other than it will «make it easier than ever for game devs to scale super resolution support across Windows devices.»

To me, that strongly suggests it will be a new API for handling upscaling, similar to that used to access AMD's FSR or Nvidia's DLSS, but it will be far more hardware-agnostic.

News that Microsoft is bringing an 'Auto upscaler' to Windows cropped up just a couple of weeks ago, and while both systems are about upscaling, DirectSR seems to be something that game developers can use as a common ground implementation. Sounds cool but we already have something like that and it's AMD's FSR.

That runs on pretty much any GPU or at the very least, any graphics card that's needed to run the latest games. But if it turns out to be better than AMD's shader-based system and it has even broader hardware compatibility, then DirectSR could well be hot news for PC gamers.

The last GDC event I physically attended was a long time ago (17 years, to be precise) but the premise hasn't changed at all: A week of seminars, presentations, and demonstrations of every aspect behind the creation of games. Sometimes you get to learn some interesting stuff and one of my favourites of all time is the detailed look behind the
