yes true most games do have a built in screen capture, but its a usually a pretty bad one. for screen shots, i would go with the link above, and if you get interested into screen capturing as in video? GoTO fraps http://www.fraps.com/ you can adjust frame rate and capture video with a click of a button! :chk: and its free.
you can make a video with that program? thats sweet, i need to make a video of some homeplay for unreal tournament, just to show how bad a$$ i am. thx
