Resolutions

Hi all
I'we got a simple question: I use see-thrug glasses, so i don't need to display the video stream fron the webcam. Can i grab the frames at 320*240 and then draw objects on a 640x480 or 800x600 window? This should cosiderably reduce the cpu load.

Bye
        Luca

It would be the same if you were using video-see through as well, you would just have to scale the camera resolution to the rendering resolution (best done using texturing).
