This tiny registry tweak shows you what resolution DLSS is rendering at

Upscaling tech has been the surprise hit of recent graphics card releases. 

Ray tracing may grab the headlines, and make for some beautiful images, but being able to run your games at higher frame rates with little noticeable difference in quality is often more useful.

Nvidia has the lead here with its Deep Learning Super Sampling (DLSS), producing far better image quality than the competition, although AMD’s FSR 2.0 is closing the gap (opens in new tab). Competition is great though and means both AMD and Nvidia are trying to perfect their technologies to get the most out of the latest games.

One frustration with DLSS is that a lot of the settings are hidden out of sight. That’s absolutely fine if you just want to get on and enjoy your games, but if you enjoy peering behind the curtain to see what’s actually happening, you can be left wanting. Until you discover this simple little registry tweak that is. 

By adding a single line to the registry, you can see what version of DLSS the game is running, which of Microsoft’s DirectX APIs is being used, and possibly most interesting of all, what resolution the game is rendering at and what it is upscaling to. This is all shown in a simple text interface in the bottom left-hand corner of the screen, and it’s easy to turn it all off again once you’ve played around a bit too.

To get up and running with this, simply hit Win + R and enter Regedit in the box. Make your way to HKEY_LOCAL_MACHINESOFTWARENVIDIA CorporationGlobalNGXCore and right-click on the right-hand panel and create a new DWORD (32-bit) Value called ShowDlssIndicator. Set the value of this to 1024 in decimal and then close the Registry Editor and you’re done.

Now when you launch a game that runs DLSS you’ll get the pertinent information in the bottom left-hand corner of the screen. Note that while this does work in Cyberpunk 2077, Chromatic Aberration makes it very hard to read, so you’ll want to turn that off. It’s much easier to see what’s happening in most other games, such as in God of War for example.

To turn it off again, just go to the same registry address and set ShowDlssIndicator to 0 or delete it completely if you prefer. Job done.
