Yesterday, AMD published the source code for FidelityFX Super Resolution (FSR) 2.0, putting the temporal upscaling tech in the hands of many more developers, and now they’ve revealed the tech has officially been made available to those using Xbox development kits. We've already heard FSR 2.0 would be included in the Xbox GDK, but it’s good to know it’s being added without delay.

We are very excited to provide #FidelityFX Super Resolution 2 to @Xbox developers! #FSR 2 can be found in the most recent GDKX samples - building cross-platform for #Xbox Series X|S, Xbox One, and Windows Desktop.
