Sony has released a substantial system update for the PS5 Pro that delivers notable improvements to the console’s PSSR (PlayStation Spectral Super Resolution) AI upscaling technology, as first reported by Push Square.
The update, version 25.01-09.20, is available to download now and weighs in at approximately 1.2 GB.
What’s New#
The headline improvement is a refined PSSR algorithm that Sony claims reduces visual artifacts in supported titles while improving temporal stability. In practical terms, this means less shimmer on fine details like hair, foliage, and chain-link fences — areas where the technology previously struggled.
Digital Foundry’s early analysis of the update found measurable improvements in titles like Horizon Forbidden West and Gran Turismo 7, with the upscaled output now coming closer to native 4K quality in motion.
Additional Changes#
Beyond PSSR, the update includes:
- Variable Refresh Rate improvements for displays supporting 48-120Hz ranges
- Quick Resume now supports up to five suspended titles, up from three
- USB audio improvements addressing latency issues reported by headset users
- General stability improvements and bug fixes
Developer Impact#
Sony has also released an updated SDK for developers, which includes the refined PSSR implementation. Studios working on upcoming titles will have access to the improved algorithm from day one, which could mean better visual quality at launch for future PS5 Pro-enhanced games.
The PS5 Pro launched in late 2024 and has positioned itself as the premium option for console gamers seeking the best visual fidelity. Sony has not disclosed specific sales figures for the Pro model separately from the standard PS5.
