I'm playing Arkham City on my PC and so far it's been running pretty smoothly but I've just hit my first major bug. After I'm done with the Ra's Al Ghul fight and he threathens Talia with a knife the game gets stuck, Batman won't let go of his sword and let me throw the Batarang. I tried lowering all my graphic settings, my resolutin and playing in windowed mode but nothing won't do. I couldn't start the game on my laptop; it would get to the part at the beginning where Jack Ryder is attacked by prisoners but the prisoners would never appear, leaving Ryder to succumb to invisible enemies. Are multi-platformed games usually this buggy on PC nowadays?
