One of the more fascinating features of the PS5 Pro, mentioned in early marketing materials and leaked more meaningfully over the weekend, is how it aims to improve unpatched PS4 games.
These titles, never updated for the PS4 Pro, stand to benefit from a toggle in the new system’s menu named ‘Enhance Image Quality for PS4 Games’. While its testing is still early, Digital Foundry explains how this works.
“In essence, the 1080p output of PS4 games goes through a post-process filter – possibly AI-based in nature – that resolves additional detail,” writes Richard Leadbetter. “I would imagine that the idea is to take legacy 1080p gaming content and to make it look better on today's 4K screens.”
