No. I'm a medium kind of guy. Might go back through on Vet. once I learn what all I'm doing, etc.
Basically just want to get through the story and then start on the multi-player.
I've noticed a few spots with some framerate dips, but there's an incredible amount of stuff going on in this game. It's rare and hasn't affected gameplay really. Maybe 3 or 4 spots over the first couple of hours.
