​ AMD FidelityFX Super Resolution 2 (FSR2) is an open source, high-quality solution for producing high resolution frames from lower resolution inputs. FSR2 uses temporal feedback to reconstruct high-resolution images while maintaining and even improving image quality compared to native rendering. ​ FSR2 can enable “practical performance” for costly render operations, such as hardware ray tracing. ​


​ While this patch targets URP 12.1.7 in particular, you can still use this patch for other versions (including newer) with a few careful changes. Note that this version of the patch supports DX11 only. ​

Integration method

  1. Apply 0001-Added-FSR2-support-for-URP.patch to your local URP repository.
    • If you can’t use git apply <path to patch> directly due to your own modifications, merge this patch into your local code manually.
  2. Apply 0001-fsr-2.2-dx11-backend.patch to FidelityFX-FSR2 @v2.2.1.
  3. Follow the build instruction from here to compile the FSR 2 API library.
    • For DirectX® 11, you should run GenerateSolutionDX11.bat instead of GenerateSolutions.bat to get the Visual Studio® solution file (.sln).
  4. Generate the VisualStudio solution (.sln) file with CMake for the plugin.

Generate VS sln

  • UNITY_PLUGINAPI_INCLUDE_DIR: Unity plugin API include directory.
  • FFX_FSR2_API_INCLUDE_DIR: FSR 2 API include directory.
  • FFX_FSR2_LIB_DIR: FSR 2 link library directory.
  • FSR2_BACKEND: Set the backend. NOTE! Currently only dx11 is supported.
  • FSR2_UNITY_PLUGIN_DST_DIR: Destination directory for compiled fsr2-unity-plugin[d].dll. ​
  1. Add FSR2Feature into your URP renderer data.Add FSR2Feature

  1. Choose FidelityFX Super Resolution 2.0 as your Upscaling Filter and turn off MSAA. ​Choose FSR2

  1. Add FSR2PassControl to GameObject where it has a camera, and you want use FSR 2 to upscale the output of that camera. ​FSR2PassControl

  • Disable all the anti-aliasing methods applied to this camera.
  • Disable any post effects, e.g. Panini Projection, that cannot be used on the same camera with FSR 2. Try to use multi-cameras and put the effect on a different camera.
  • If you want FSR 2 to automatically generate reactive mask for you, you should make sure Output Reactive Mask is checked. Otherwise, you should provide your own masks with ReactiveMaskParameter.OptReactiveMaskTex and ReactiveMaskParameter.OptTransparencyAndCompositionTex.
