Today, AMD announced the availability of FSR 2.1, an updated version of the FidelityFX Super Resolution image reconstruction technique.
According to AMD, FSR 2.1 focuses on improving the algorithm’s quality and reducing artifacts like the dreaded ghosting and shimmering.
| CHANGE | IMPACT |
| Motion vector divergence used to diminish locked pixels | This should alleviate ghosting issues on geometry with motion vectors not matching underlying pixel colors. |
| Disocclusion logic is now able to detect disocclusions in areas with only small depth separation between objects. | This should alleviate ghosting issues and improve upscaling quality on some disocclusion cases. |
| Improved upscaled output quality by turning some half-precision computations to full precision. | This should improve overall color range and temporal stability of the upscaled image produced. |
Reactive Mask updates:
|
This should alleviate ghosting issues on transparent geometry such as particles. |
| Composition and Transparency Mask updates:
Dilation now based on input colors to avoid expanding of lock diminishing into non-relevant areas of the upscaled output. |
This should alleviate ghosting issues on geometry with motion vectors not matching underlying pixel colors. |
The FSR 2.1 sample also now includes animated textures, spark particles, smoke particles, and the generation of Reactive Mask and Composition and Transparency Mask resources. The Reactive Mask in particular is said to be key to getting a high-quality upscaling result.
AMD says game developers should find updating from FSR 2.0 to FSR 2.1 simple, especially since the application side of the API has not received changes. In fact, a game already supports the new version: Giants Software’s Farming Simulator 22. You can check out an official video comparison below.
AMD says 20 games support FSR 2.0 right now, while another 25 soon will.
