AMD releases full FSR3.0 source code for DX12 and Unreal Engine 5

AMD is making the source code for FSR3.0 public today.



AMD has released full source code for DirectX12 and Unreal Engine 5 implementation of its latest temporal upscaling technology called AMD FidelityFX™ Super Resolution 3 (FSR 3). Developers and enthusiasts alike can now try implementing this technology into their games and software. This also marks the first time any company is publishing its Frame Generation technology as open source.

The FSR3 is considered a successor to FSR2 and it supersedes FSR2 implementation. The Frame Generation component is optional to use, but FSR3 upscaling will still work regardless. AMD is providing source code and DLL files for developers to implement this upscaling technology manually, or through DLL library update. For games that already have FSR2 support, AMD recommends replacing FSR2 with 3.0

AMD confirms that this version of FSR3 brings improvements over the initial release previews, as featured in two launch titles: “Forspoken” and “Immortals of Aveum”. The company confirms that engineers were working on improving quality with V-Sync enabled when using high refresh rate monitors.



In optimizing performance, AMD advises using asynchronous compute with FSR 3. However, integrating this in a single step can pose challenges for certain engines. To simplify the process, there is now the option to execute Optical Flow and Frame Interpolation workloads on the primary graphics queue designated for presentation. This approach may deliver lower performance, but it requires less memory and should perform better.
