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.
Minimum Prerequisites
- Visual Studio 2022 (Install
vcpkg package manageras part of the install process) - Windows 10 SDK 10.0.18362.0
Download
We offer a single minimal packaged download for this release of the FSR SDK, which contains the pre-built, signed DLLs and sample library:
- Minimal package ~100MiB
That contains everything required to get started with the AMD FidelityFX SDK but does not include the media assets used in the samples. Included is the AMD FSR Media Delivery System that you can use to download the media assets, which is required before any of the samples will run.
