Tomorrow brings the 4.5 update to PlayStation 4 and PS Pro, and with it comes improvements for the PSVR experience, boost mode for PS4 Pro, and more.

Boost mode (toggled on in the system settings) improves older titles that have not received a PS4 Pro patch. While not applicable to all legacy titles, Boost mode should provide framerate stability and possibly faster load times.

Also included in the update is external hard drive support, improved screen resolution when coming out of VR mode, custom wallpapers, voice chat for remote play, updates for some apps, and more.
