Improvements via the patch are as follows:

Resolution increased to 1440p 1080p supersampling Improvements in shadow quality Improvements to draw distance Improved motion blur effects

4K televisions users will see a benefit in a locked 30FPS with full V-sync.  A welcome improvement as screen tearing was quite apparent with the launch version of the game, although base Playstation 4 users will still see occasional tears when frames drop below target.

Interestingly there have been a few drawbacks with the update on the more powerful hardware as Digital Foundry noticed that the Playstation 4 Pro version suffered a loss in performance in the more action based areas of the game with drops in frame rate hitting as low as 26FPS when compared to the base Playstation’s 30FPS.
