Several attacks, Rose’s Soul Throw in particular, make no damage. She performs the move, but the game doesn’t consider it to be a successful attack and doesn’t reduce the opponents life bar.
I personally had this problem when I tried to play offline after installing the game. When I logged in to my Windows Live account, the game made me install an update and the problem was gone.
Now I’m trying to play with my brother who has a very low-end PC. The maximum rating given by the benchmark, after several hours of tweaking and tremendously overclocking the video card, was B. He claims to have applied the patch offered by the Windows Live, because the game wouldn’t have let him to connect, but Rose’s Soul Throws are completely useless both online and offline.
My PC doesn’t have this problem, it only does when I play online against my brother.
Anyone has an idea why this is so?
