I just made a new game, saved it and reloaded. Worked instantly. Then I stayed ingame and loaded my normal game with 16 hours playtime. Loads until 3/4 and stays there for 30 seconds but then it loads it without crash. Loaded the new game again, worked instantly but another load to the old crashed it. Some guy said he made a new game and played that until finishing act 1 without a crash. So if they can't fix it we all have to make a new game and all the playtime is fucked up. What is so different between the EA and the final release that they didn't know about this specific problem that makes the game near umplayable.
