I bought this game at release. 1,5 month ago. Still nothing to solve the painfull framerate.
I can't play this game.
Do something for the people who bought your game. The people who are feeding you. Because I regret it now and I'll never buy one of your game again at this point. One day you will ask yourself why people doesn't support you anymore and doesn't pre-order your work anymore, that's because we don't spit in the hand that feed us.
Polish your game, test it, don't launch it if it is half-finished.
If you need some PS4 developing skill, call some talent guys, call Rocksteady for example.
