Sony really should just announce the features that they’re going to be putting into system software betas for PlayStation 4, because as soon as the beta updates roll out to those signed up (and are under NDA), the details leak.
The upcoming 5.50 system update will add a system-wide supersampling option for PlayStation 4 Pro. This will let you force games that support higher than 1080p resolutions to run at higher resolution and then scale it back down, giving a smoother image and helping to minimise aliasing. It’s something of an edge case, as most PS4 Pro enhanced games already either run with supersampling or have options that let you choose between this and enhancing graphics or performance at 1080p.
Sony note that “Results may differ depending on the games. In some games, image quality may not improve, or the frame rate may change.” Read that as the frame rate potentially worsening.
Elsewhere, My Library has been spruced up with the ability to distinguish between games purchased with your cold hard cash and that have been added to your library as part of PlayStation Plus, and you will also be able to hide unwanted games from your library, meaning you can finally delete all those blasted demos and betas that clog things up.
