PS4 update 4.50 will add boost mode, which will increase framerate for all games on the PS4 Pro

Sony recently announced what will be coming in the 4.5 system update for the PlayStation 4 which included external HDD support, custom wallpapers, and more. Thanks to NeoGAF there could be even more to this update that’ll be huge for the system.
PS4 Pro will receive a “Boost” mode in PS4 4.50 that increase the framerate of games without Pro support.

We have yet to hear more about this, but will update when we do so from Sony.
