AMD has just announced its FidelityFX SDK 2.0, along with the availability of FidelityFX Super Resolution 4 for developers, which paves the path for next-gen Neural Rendering technologies & FSR Redstone.

AMD's FidelityFX SDK 2.0 Launched: Adds Support For FSR 4, Neural Rendering Technologies, FSR Redstone & Much More

At Gamescom 2025, AMD is going big with its FidelityFX suite, which is receiving the 2.0 update. With this new update, developers will now be able to access various technologies such as the upcoming ML-based neural rendering tech and FSR Redstone. With the SDK, developers will be able to easily integrate these into their games.

The following are the key changes in FidelityFX SDK 2.0:

You can download the SDK v2 package here, read the FSR 4 Documentation here, and also view the SDK 2 on GitHub here.

In addition to the SDK, AMD is also adding its latest FSR 4.0.2 in GPUOpen, allowing developers to access the latest upscaling and frame-generation methods. As detailed before, FSR 4 is a vastly improved scaler, using ML/AI for upscaling. The image quality has been improved significantly versus the older FSR 3. The list of changes/improvements includes:

The following is a difference between FSR 4 and FSR 3 upscaling:

Developers will have a lot of ease when switching from FSR 3.1 to FSR 4 since it is based on the same API. FSR 4 is also available as pre-built, signed DLLs as part of FidelityFX SDK 2.0, and there's also a UE (Unreal Engine) specific plugin which supports version 5.1 to 5.6.

AMD's FidelityFX SDK 2.0 with FSR 4.0.2 upscaling will require a Radeon RX 9000 Series GPU or above, while FidelityFX SDK 2.0, with FSR 3.1.5 upscaling/frame-gen will require a GPU that supports Shader Model 6.2 or above. With this announcement, it looks like we are one step closer to the launch of AMD's FSR Redstone update, which should bring them closer to NVIDIA's in terms of neural rendering techniques.
