Hi Peiman,
I wouldn't recommend using screencapturing for "video-recording".
Depending on the implementation you've chosen, the file format you are
saving to and the computer configuration this might simply be to slow.
For recording the screen use something like FRAPS or NVidia's built-in
recording.
You are not giving enough details to get more help on this.
Cheers

I guess the copy to host-memory and saving the file is the bottleneck
here. Are you trying to record every frame?
