We learned from NeoGAF that a new update for PlayStation 4 has been officially made available, firmware update 4.74. This update doesn't introduce any new features, but aims to improve system performance.
Reading the NeoGAF thread, we discovered that what seems like this firmware update actually appears to be particularly effective for Destiny 2, as, some users have written, this new update the game is no longer affected by crashes. It is, of course, hard to say whether this anecdotal evidence actually holds water, or if it's unrelated.
Did you notice any other differences after you upgraded your console firmware to version 4.74?
