I honestly wouldn't be shocked if there was a day 1 patch to fix some of this stuff. Those seem to be all the rage these days, after all. Something like that, plus a driver update from Nvidia/AMD would probably go a pretty long way. In all seriousness though, there's also a decent chance that some of the problems stem from the whole shady, leaked copy thing. I'll reserve judgement until it's officially out on Tuesday, but my expectations are going to be a bit lower going in now.
