Merged today to Mesa 22.2 was a four month old merge request for the open-source Radeon Vulkan driver "RADV" that significantly improves the 16-bit FidelityFX Super Resolution (FSR) performance.

FidelityFX Super Resolution (FSR) already performs well on Linux while now with Mesa 22.2's RADV it will see significantly better performance for the 16-bit version of this open-source technique for high resolution image upscaling for games.

Daniel Schürmann who made this improvement for RADV found that the patches improve the 16-bit AMD FSR performance by around 35%!

The patches are around NIR intermediate representation vectorization and lowering for this Radeon Vulkan driver that help out the 16-bit FSR path in particular.

Mesa 22.2 with these patches and a lot more to the Radeon, Intel, and other open-source 3D drivers will debut as stable around August.
