I picked up darksiders this weekend. $15 on steam. Game is pretty fun. Very smooth and fluid god of war~ish combat, decent puzzling and pretty good voice acting as well. I like the art style they went with too.
I was testing out various nvidia inspector settings on my laptop running it last night and was surprised that I didn't see any difference between totally off and all the quadrouple super duper mega transparency optimus prime anti alias sampling @ 1080p.
