The PlayStation 4 will be updated to add new features and enhancements to the broadcast on Twitter and social networks.
Initially, the device supports a 60-fps SWITCH on 1080p resolution, which means a smoother display of video, especially in combat games.
About notifications only you can see them from the QuickList without having to go to the main screen menu.
One of the new features is the follow button to follow the user without becoming a friend on Facebook and as with the Xbox, the follow-up is only available to authenticated accounts and celebrities to be made available to everyone later, and you can also block annoying users.
Sony will add support for multiple disks with or without additional content. Sony has not yet officially scheduled the update to all users, but is expected soon with an improved app store design.
