Today Sony Interactive Entertainment made the system software upgrade 5.55 for its PS4 available for download to the PlayStation Network.
The upgrade is somewhat larger than usual in document size, weighing exactly 460.1 megabytes. Yet, the patch notes are as streamlined as usual, hinting to unspecified improvements to the platform performance.
YAnd as normal, you ought to remember this generally means that the operation of the operating system itself continues to be enhanced, not all those games, so don’t expect better frame rates or whatever will make the real games better.
In the present time of the writing the update isn’t yet on the applicable Sony sites, and also you will need to use the option in the preferences of your PS4 or PS4 Pro to start the download of this upgrade and start the setup. Later today you should be in a position to download the update from here if you’re in North America and from here if you are in Europe.
