AMD’s promise regarding significant advancements in artificial intelligence (AI) didn’t take long to materialize. In a surprising announcement, AMD unveiled the latest iteration of its FidelityFX Super Resolution technology: FSR 3.1. Showcasing substantial improvements in image quality and beyond, this is an exciting development.

The announcement of AMD FSR 3.1 isn’t merely about incremental enhancements to the supersampling algorithm of the technology. AMD has also added its own version of Nvidia’s DLAA anti-aliasing solution, as well as decoupled the upscaling feature of FSR from its frame creation capabilities.

Effectively, this allows Nvidia GPU owners to choose and match between Nvidia’s native solution and AMD’s in fully supported games, which is a significant advantage for performance and image quality comparisons.

AMD FSR 3.1 Improvement

Overall, AMD FSR 3.1 delivers improvements in the following areas of image rendering:

Enhanced temporal stability, resulting in substantial reductions in flickering, shimmering, and blur around moving objects.
Reduced ghosting and better detail preservation.
FSR 3.1 frame creation now works with other upscaling solutions, such as Nvidia’s DLSS and Intel’s XeSS.

AMD has also released a new AMD FidelityFX API, which should make it easier for game developers to debug and ensure forward compatibility with the latest versions of FSR. Additionally, FSR 3.1 will be available for further integration into Vulkan and Xbox GDK later this year, significantly bolstering the practical scope of these features.

All of this would be irrelevant if AMD didn’t have something to back up its claims, of course. Nvidia’s DLSS is a proven upscaling solution and the gold standard in this niche, and competing with it is no easy task. Perhaps surprisingly, then, AMD’s video demo shows remarkable improvements in all areas.

For a brief glimpse of what we’re talking about, just look at AMD’s own announcement, which directly compares FSR 2.2 with FSR 3.1 on a sample from Ratchet & Clank: Rift Apart.

AMD demonstrates remarkable improvements in terms of temporal stability and ghosting reduction, but the truly impressive part is that the showcased GIF was taken from a game rendered at 1080P resolution, with FSR running in Performance Mode, of all things. Truly impressive.
