I wasn't sure if Help/Advice would be appropriate, since this seems to be a technical/software related issue, if I'm wrong, I apologize. Anyway, I bought Assassins Creed 2 during the Steam summer sale, but the game is basically unplayable due to some strange bug/incompatibility issue.
I'm playing on an Asus G73JH, with a ATI Mobility HD5870. My drivers are up to date, and I've toyed around with all the graphics setting to no avail, I even tried reinstalling the game. No luck.
I've never had any graphical issues with the laptop so far, so any help would be appreciated.
