Warner Bros. has released the update to PS4 players, along with the following blog post:
Today we released an update for Batman: Return to Arkham that will add visual upgrades for the PS4 Pro, as well a variety of performance and stability improvements. The PS4 Pro updates will provide increased visual fidelity for those playing the game on a PS4 Pro console.
Other improvements addressed by the update include:
- Performance / hitching issues have been improved for a more smooth and consistent framerate.
- Intermittent crashing issues have been addressed to provide improved gameplay stability.
I have yet to play a PS4 Pro, but from what I have seen of them in demos, they seem pretty impressive, but is it really worth the extra money?
