Sony PlayStation lead system architect Mark Cerny has done an in-depth interview with Digital Foundry. The full discussion isn't out yet, but a few very interesting tidbits have been released regarding Sony's latest PSSR upscaling technology for the PlayStation 5 Pro, the related Project Amethyst collaboration with AMD, and how that all ties in with FSR upscaling on the PC.
Indeed, one of the pressing unknowns that Digital Foundry wanted to clear up was the relationship between Sony's newly upgraded PSSR upscaling and FSR Redstone, the latter being the latest machine learning-based build of AMD's upscaling tech for the PC.
