The patch notes are straightforward, stating simply, “This system software update improves system performance.” The PS5 patch was similarly cryptic, despite the fact that the new system necessitates a much larger 941MB download. Given the lack of detail, both updates are more than likely just normal speed enhancements rather than solutions for any major concerns with either system. However, it’s plausible that Sony was attempting to get ahead of a known flaw before too many gamers were aware of it.
Wednesday morning was an especially hectic period for PlayStation upgrades. Sony started with a performance-enhancing PS5 firmware update. Following that, the company launched a similar update for the PlayStation 4. The PlayStation 4 firmware update 9.03 was published on December 1st. Despite being a necessary download, the 490MB patch does not add much to the game. The update should install automatically as long as the PS4 has an internet connection.
