AMD has announced FidelityFX Super Resolution 2.1 – an updated version of its temporal upscaling solution.
Here is the list of major changes FSR 2.1 introduces:
- Motion vector divergence used to diminish locked pixels.
- Disocclusion logic is now able to detect disocclusions in areas with only small depth separation between objects.
- Improved upscaled output quality by turning some half-precision computations to full precision.
- Reactive Mask updates.
- Composition and Transparency Mask updates.
Most of the changes are meant to alleviate ghosting issues, improving overall quality.
In addition to this list, the sample has been updated to include examples of animated textures, spark particles, and smoke particles. The UI has options to disable use of the masks, so developers can see the quality improvements when the masks are provided to the FSR 2 API.
AMD says that updating to FSR 2.1 from 2.0 should be simple, and developers should pay particular attention to the changes to the Reactive Mask to get the best quality upscale.
Apart from the FSR 2 source code, the company also updated the Unreal Engine plug-ins, so you can now upgrade to using FSR 2.1 in your Unreal games for UE 4.26, 4.27, and UE 5. You can already see FSR 2.1 in the latest 1.7.1 patch for Farming Simulator 2022.
