Well, it stopped doing it for the most part so I don't know what was up with that. It seems almost like what I said before: if I let it sit for a few seconds after loading,it's fine. Whacked.
To be perfectly honest, performance isn't quite what I'd like. It's not bad by any means (always above 30fps, usually between 45-70) at 1024x768 with everything maxed. I really can't expect anything more than that, but it's so atmospheric it almost seems like a waste to not be playing it at 1280x960. Still, it seems great so far.
And that's pretty much that for now. I have so much other stuff to play I'm putting this on the back burner for the time being. It's great, but I still have to finish FEAR, get bored of Oblivion, and finish GoW.
