2) 3D Blu-Ray support for PS VR
Doing double duty as a decent Blu-ray player has long been one of the PlayStation 4's added bonuses - and, now, PlayStation VR owners are set to get a second treat.
Aside from an improved resolution in Cinematic mode, with boosted frame-rates at lower screen sizes, update 4.5 will also deliver 3D Blu-ray support for PS VR.
No longer will you need to don those low-spec, erm, specs: strap on your PS VR headset and you'll be able to enjoy full, stereoscopic 3D Blu-ray through your PS4.
Sure, it's an expensive way to attain 3D viewing - but, for existing PS VR owners or those wanting 3D that doesn't come from an ailing flat panel, this is a solid solution.
3) Boost mode for PS4 Pro
Got yourself a PS4 Pro? Older games will now play better - all thanks to the new Boost Mode, introduced in the 4.5 update.
In essence, Boost Mode is Sony's answer to calls for repurposed content for the Pro model. Rather than necessitating the reworking of entire games, Boost Mode sees the PS4 Pro run legacy titles - those developed before the PS4 Pro was released - at higher frame rates, as well as potentially slashing load times.
It's not, though, guaranteed to work with all games - and might deliver a few glitchy moments in older titles. When that happens? Simply switch Boost off and your Pro will emulate a standard model PS4.
Sure, it's not a perfect answer, but it does at least mean that all of the Pro's extra power isn't going to waste.
