AMD has announced that FidelityFX Super Resolution (FSR) 2.0 is now open source, allowing anyone to take an intimate look at the latest iteration of red team’s cutting-edge upscaling technology that adopts temporal upscaling techniques to deliver what the company says is similar or better than native image quality while boosting the frame rates of supported games that now include God of War and Farming Simulator 22. The source code has been made available via GPUOpen under the MIT license, and enthusiasts can find links to it on AMD’s dedicated FSR 2.0 page, which can be found here. AMD’s announcement of FSR 2.0 comes exactly one year after the introduction of its spatial-based predecessor. The FSR 2 page at GPUOpen has also been revised with new screenshot comparisons and other updated content.

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. For DirectX 11, developers should contact their AMD representative.
