Utilizing AMD's New SDK to Integrate FSR 4 into Games Running FSR 3
A new method allows gamers to apply AMD's FSR 4 technology into games that run on FSR 3, using a straightforward process involving DLSS Swapper and file modifications.
With the launch of AMD’s RDNA 4 GPU architecture and its FSR 4 technology, AMD introduced significant enhancements to its upscaling capabilities using machine learning. However, accessing FSR 4 requires developers to incorporate it into their titles.
Recent insights show a workaround using the latest FidelityFX SDK, enabling players to independently integrate FSR 4 through a tool known as DLSS Swapper. This utility allows users to modify DLL files within a game’s directory, making it possible to swap out FSR 3 for FSR 4.
Steps to Implement FSR 4:
- Download and install DLSS Swapper.
- Obtain AMD’s FidelityFX SDK and extract the files.
- Navigate to the
Kits\FidelityFX\signedbin\
folder. - Rename
amd_fidelityfx_upscaler_dx12.dll
toamd_fidelityfx_dx12.dll
. - Open DLSS Swapper, select FSR 3.1 DirectX 12, and import your modified DLL.
- Your game should now have FSR 4 listed in its options.
Important Note:
Be cautious as modifying DLLs does not guarantee that your GPU will support FSR 4; it’s crucial that your hardware is compatible. Initial tests have mainly confirmed these methods working with a limited selection of titles.
