AMD FSR™ API

  • Minor non-API breaking additions:

Updated Components

Starting with AMD FidelityFX™ SDK 2.0.0 the effects, previously combined in amd_fidelityfx_dx12.dll, are split into multiple DLLs based on effect type. Please see Introduction to FSR™ API for details.



PDBs are provided for the loader DLL.

Updated documentation

  • FSR™ Upscaling 4.1 documentation.
  • FSR™ Ray Regeneration documentation.

Deprecated effects

None.

Deprecated components

All SDK version 1 effects are now deprecated to that version of the SDK. For any pre-existing FidelityFX features (including the legacy FidelityFX Super Resolution sample), please refer to FidelityFX SDK 1.1.4.
