Building on the success of FSR 2

Earlier this year, we announced AMD FidelityFX Super Resolution 2 (FSR 2), with the source code and plugin for Unreal Engine available here on GPUOpen from June onwards. The rate of adoption from game developers has been exceptional – as of today, FSR 2 upscaling technology has been announced for 45 available and upcoming games, with 20 of those already available now!

As we stated in our FSR 2 source code release post, we are always making improvements, and today we continue in that effort by releasing our first major update with FSR 2.1. In fact, you can see FSR 2.1 for yourself in the latest 1.7.1 patch for Farming Simulator 2022, released earlier this week by Giants:

What’s new with FSR 2.1?

FSR 2.1 includes significant changes to certain parts of the algorithm which allows games to further increase quality and reduce artefacts such as ghosting or shimmering. Take a look:

In addition to the above major changes, the sample has been updated to include examples of animated textures, spark particles, and smoke particles. The generation of Reactive Mask and Composition and Transparency Mask resources are also now included. The UI has options to disable use of the masks, so developers can see the quality improvements that come to the upscaled output when the masks are provided to the FSR 2 API.

Lastly, FSR 2.1 includes many small bug fixes, as well as documentation fixes and improvements.

The application-side FSR 2 API has not changed, so updating to FSR 2.1 from 2.0 should be simple. Developers should pay particular attention to the changes to the Reactive Mask to get the best quality upscale. If there are any issues, please reach out to your AMD representative for assistance.

We’ve also updated our FidelityFX Naming Guidelines for FSR 2 – make sure you take a look.

Unreal Engine FSR 2 plugin updates

As well as updating the FSR 2 source code, we’ve also updated our Unreal Engine plugins as well, meaning you can now upgrade to using FSR 2.1 in your Unreal games for UE 4.26, 4.27, and UE 5.

It’s important that we draw your attention to the documentation for our updated plugins. We’ve provided a lot of new information on performance recommendations and known issues in our how-to guide, which we strongly recommend you read in order to get the best performance from FSR 2.1.

This includes highlighting new patches for Unreal Engine (which you can find in the plugin package) to help improve things for your game even further. A more detailed guide on using these will appear on GPUOpen in the near future.

Thank you!

And finally, we must thank those in the community who have taken the time to file issues on the GPUOpen FSR 2 GitHub repository. It is very much appreciated. Many of those issues have fixes included within FSR 2.1.
