AMD Makes FSR 2.0 ‘FidelityFX Super Resolution’ Open-Source, Source Code Officially Published

FSR 2.0

Today marks one year since AMD launched its FSR 'FidelityFX Super Resolution' technology and to celebrate the occasion, the company has published the source code of FSR 2.0.

AMD FSR 2.0 'FidelityFX Super Resolution' Goes Open-Source Today

Press Release: Today marks a year since gamers could try out AMD FidelityFX Super Resolution technology for themselves with our spatial upscaler – FSR 1. With the introduction of FSR 2, our temporal upscaling solution earlier this year, there are now over 110 games that support FSR. The rate of uptake has been very impressive – FSR is AMD’s fastest adopted software gaming technology to date.

So it seems fitting that we should pick this anniversary day to share the source code for FSR 2, opening up the opportunity for every game developer to integrate FSR 2 if they wish, and add their title to the 24 games which have already announced support.  

As always, the source code is being made available via GPUOpen under the MIT license, and you can now find links to it on our dedicated FSR 2 page.

Along with the FSR 2 API, and the full C++ and HLSL source code behind it, you’ll also discover our Cauldron-based sample and comprehensive API documentation to help you with your integration. We put a lot of effort into the documentation to help developers with their integrations as much as possible, so you can add FSR 2 to your game or engine and really achieve the highest possible quality. Please check it out! 

The version you’ll be downloading today from GitHub is v2.0.1, which reflects the ongoing improvements we’ve been making since you would have first seen FSR 2 in action earlier this year. 

FSR 2 supports both DirectX 12 and Vulkan, with plugins for Unreal Engine 4.26/4.27 and Unreal Engine 5 due very soon. It will also be available through the Xbox Game Development Kit.  We’ve also updated the FSR 2 page here on GPUOpen – you’ll find new screenshot comparisons and updated content.

Note that FSR 1 can still be exposed as its own upscaling option in addition to FSR 2 in-game titles. Both technologies have different characteristics which may be suitable for a wider range of platforms and user preferences. For example, our FSR 2 partner title DEATHLOOP exposes both.

FSR 2 technology has been developed from the ground up, and is the result of years of research from AMD. It has been designed to provide higher image quality compared to FSR 1, our original open source spatial upscaling solution launched in June 2021.

Note that FSR 1 can still be exposed as its own upscaling option in addition to FSR 2 in game titles. Both technologies have different characteristics which may be suitable for a wider range of platforms and user preferences. For example, our FSR 2 partner title DEATHLOOP exposes both!

Supports:

  • DirectX® 12.
  • Vulkan®.
  • Coming soon: Unreal Engine 4.26/4.27 and Unreal Engine 5 as a plugin from the Unreal Marketplace.

Download the latest version - v2.0.1

  • FSR 2.0.1 API for integration.
  • API documentation including quick start checklist – it is strongly recommended to consult this to ensure best upscaling quality!
  • Full C++ and HLSL source provided via a library.
  • Samples provided for DirectX 12, and Vulkan.

We’re really excited to finally get the source code, docs, and the sample out to developers, so head over to our updated FSR 2 page now to see what’s new!
