FRAPS Question

Hello I have been trying to record FRAPS with Antialiaisng on. only 2x. the FPS drops 400 to 2. Literally. but if i don't I get about 140 fps.

but however, 4x antialiasing, i get 2 fps. I think its a bug. Anyone have a solution? Thanks! I appreciate it


What game and video card? Cause anti-aliasing is kinda intense on a video card, especially if it's an ATi card. If your card can barely handle the game, then you AA will crush the card.
