AMD FidelityFX Super Resolution 2 (FSR 2) is our open source temporal upscaling solution. FSR 2 uses cutting-edge temporal algorithms to reconstruct fine geometric and texture detail, producing anti-aliased output from aliased input.

  • Supported Engine Versions

AMD FidelityFX Super Resolution 2 is our temporal upscaling technology designed to deliver high image quality and boost framerates across a wide range of products and platforms. 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 that launched in June 2021. As with FSR 1, FSR 2 is open source.

This plugin integrates FSR 2 into Unreal Engine 4 as of version 4.26.2 (or higher) and Unreal Engine 5 for versions up to version 5.3.
