AMD FSR 4 running on PlayStation 5 Pro promises to be more interesting than anticipated, judging from what a well-known insider revealed recently.

Speaking on the NeoGAF forums, known AMD insider KeplerL2 commented on the recent announcement that the next version of the AMD upscaler is coming to PlayStation 5 Pro next year, saying that the system cannot run the model that is being used by the upscaler to run on RDNA4 GPUs. Sony and AMD started working on the mid-generation refresh before AMD decided to move FSR to an ML model, and when the company made the switch, the PlayStation 5 Pro design was done with no FP8 support. As such, it will be very interesting to see how running the full-fat version of the upscaler on the system will be achieved.

Those expecting to see games that support the AI-powered PSSR on PlayStation 5 Pro to automatically support AMD FSR 4 without developer intervention, however, may be disappointed. As far as KeplerL2 knows, the current version of the PlayStation Spectral Super Resolution upscaler doesn’t allow system-level DLL swaps, so there’s a very likely chance that developers will have to update already released games if they want to take advantage of AMD FSR 4 once it becomes available for the system in 2026.

Besides offering the aforementioned AI-powered PlayStation Spectral Super Resolution upscaler, whose implementation has been hit and miss, depending on the game, the PlayStation 5 Pro offers other improvements that make it the system of choice to enjoy PS5 games at their very best.
