This update brings with it the ability to use an external HDD to store and play games.
It also brings with it “boost mode” to the PS4 Pro; which increases performance for most games in the PS4 library. I’m no tech head but here’s what the official blog says about boost mode;
PS4 Pro gets a new feature in this update called Boost Mode. This feature has been designed to provide better performance for select legacy titles that have not been patched to take advantage of the PS4 Pro’s faster CPU and its faster and double-sized GPU.
This can provide a noticeable frame rate boost to some games with variable frame rates, and can provide frame rate stability for games that are programmed to run at 30 Hz or 60 Hz. Depending on the game, the increased CPU speed may also result in shorter load times. You can turn on Boost Mode by going to Settings > System.
Finally (but not really) it improves the picture quality of theatre mode and allows PSVR users watch 3D Blu Rays.
Some of the less exciting things the update brings is custom wallpapers, voice chat on PC/Mac when using remote play and a quick menu refresh!
Make sure you put your PS4 on rest mode – tomorrow is a big day!
