Assassins Creed Unity had a few issues running on PS4 and Xbox One and since it’s release, the game continues to offer unstable performance. Thanks to the recent release of the PS4 Pro 4.50 Beta a number of games are benefiting from a feature called ‘Boost Mode’ that pushes the PS4 Pro to work with older PS4 games.
The end result is games running better and feeling more responsive to play. AC Unity is an example of this, with frame rate being a stable 30FPS now ensuring responsive controls and no issues like V-Sync & Screen Tearing.
