I just downloaded the game, but the moment after I exit the character creator, the camera just spins around which makes it unplayable. I can't turn it off or anything either. Lowering the mouse sensitivity somewhat helps, but that can make fighting enemies very difficult. Even at 0, the camera still spins, but it's not as bad. Still impossible to play without getting a headache though.
I was looking so much forward to playing it too, so this is just very disappointing that it has a bug like this.
