AMD brings FSR 4 to developers with its FidelityFX SDK 2.0
AMD’s FSR 4 tech is now Open Source through GPU Open
With the release of AMD’s FidelityFX SDK 2.0, AMD has finally opened up its FSR 4 (FidelityFX Super Resolution 4) AI upscaling technology to developers. Now, developers can directly integrate FSR 4 into their games using prebuilt, signed DLLs. However, AMD’s FidelityFX API will allow for driver-based FSR 4 upgrades in the future using AMD’s FSR Upgrade feature.
This SDK release opens the door to direct AMD FSR 4 integrations into games. Until now, FSR 4 support has relied on AMD’s FidelityFX API, which can be used to upgrade games from FSR 3.1 to FSR 4. Soon, games will be able to support AMD’s FSR 4 technology by default. This means that future games will not need supported FSR 4 drivers to enable FSR 4 upscaling.
AMD has also released a new Unreal Engine 5 plugin that can enable FSR 4 in Unreal Engine 5.1-5.6.
The AMD FidelityFX SDK v2.0 update includes our cutting-edge ML upscaler AMD FidelityFX Super Resolution 4 (FSR 4).The new ML-accelerated AMD FSR 4 upscaling algorithm is trained using high-quality ground truth game data on AMD Instinct GPUs. FSR 4 uses the hardware-accelerated features of the AMD RDNA 4 architecture designed to give the user maximum upscaling quality while still providing a next-level gaming experience with a substantial game performance boost.
Visual fidelity improvements
AMD FSR 4 delivers a significant image quality improvement over FSR 3.1 upscaling, with the ML-based algorithm designed to help improve temporal stability, better preserve detail, and reduce ghosting.
Reduced ghosting on moving objects
AMD FSR 4 reduces the ghosting on moving objects and eliminates artifacts from disoccluded surfaces when compared to FSR 3.1. This significantly improves the image quality while playing.

Expect FSR 4 adoption to explode
Now that FSR 4 is available through AMD’s FidelityFX SDK 2.0 and an Unreal Engine 5 plugin, developers can now integrate FSR 4 into their games without relying on AMD drivers and AMD’s “FSR 4 Upgrade” feature. This is great news for gamers, though it is worth noting that FSR 4 support remains limited to DirectX 12. This means that FSR 4 still cannot be integrated into games that use the Vulkan API. This includes games like DOOM: The Dark Ages.
Neural Rendering
With AMD’s FidelityFX SDK 2.0, AMD has taken steps to pave the way towards AMD’s FSR 4 “Redstone” AI technologies. This will allow AMD’s drivers to upgrade games to use AMD’s upcoming ML Frame Generation technology. It will also allow AMD’s drivers to upgrade to the latest version of other ML technologies, including FSR 4 upscaling, to deliver better visual results. This should also apply to other AMD FSR 4 “Redstone” technologies like Ray Regeneration and Radiance Caching.
