I am fairly new to windows 7. When I started playing crysis 2 the game minimized down and there was an error saying that I am using up too many resources graphically. It also mentioned switching to windows 7 default theme. I am using a third party theme. Is this normal? I did not see and significant drop in performance when I was playing crysis so I'm assuming it just doesnt like this thrid party theme. I disabled the error message.
