how to record in game video without the lag on fps?

[IowaBoy]

title says it all. my fps is about 120-170fps, and when i turn on a cam i go down to 30-50fps(xfire cam) and about 20-130fps(cam studio, goes up and down and lags)

Is that 'cam studio', Camtasia Studio?
Anyway, there's really no way to circumvent the lag when recording video in a game. The recording & encoding process takes up a nice chunk of your CPU & disk bandwidth.

Things that may help is lowering your game resolution, and playing in a window.
Usually that doesn't help, but it has helped for some.

the camstudio is camstudio...with the xfire if i change the record to just 10 fps i still get all the lag in the fps on game...tried gamecam and got a error with cod so i unistalled it.
