Speaking during an interview with Digital Foundry, Mark Cerny, the lead architect on the PS5, has stated that the format holder sees FSR 4 as the ‘next evolution’ for PlayStation Spectral Super Resolution (PSSR), and hopes to have something similar to its upscaler available for the PS5 Pro as it looks to 2026 and beyond.
The neural network (and training recipe) in FSR 4’s upscaler are the first results of the Amethyst collaboration. And results are excellent, it’s a more advanced approach that can exceed the crispness of PSSR. I’m very proud of the work of the joint team!

Our focus for 2025 is working with developers to integrate PSSR into their titles; in parallel, though, we have already started to implement the new neural network on PS5 Pro. Our target is to have something very similar to FSR 4’s upscaler available on PS5 Pro for 2026 titles as the next evolution of PSSR; it should take the same inputs and produce essentially the same outputs. Doing that implementation is rather ambitious and time consuming, which is why you haven’t already seen this new upscaler on PS5 Pro.
As previously reported, Sony and AMD have teamed up for Project Amethyst, with the PlayStation manufacturer having contributed to the development of FRS 4, which is a new machine-learning upscaler that is comparable in performance to Nvidia’s DLSS. This collaboration is expected to define the architecture of the PS6, which is heavily rumoured to utilise AMD’s UDA GPU architecture alongside either a Zen4 or Zen5-era CPU.
