On my Vista, Empire at War, Freelancer, and NWN2, all work great, (except I have to turn down all the graphics settings to their lowest settings for NWN2), but Knights of the Old Republic isn't working very good. I can get all the way through Taris fine, but once I get to Dantooine it's completely unplayable because of how horribly laggy it is. I'll start walking, but I won't move, so I take my hand of the key, and then a second later all be all the way on the other side of the map. I've turned all the raphic settings to thei lowest and it's the same. It really bothers me.
