That data has to travel from the camera to the cRio then to the laptop.

The webcam is hooked up to a switch on the robot, so the driver station can http get an image from the webcam without the cRio in the middle. A good driver station laptop can grab an image, process it, and send the results back to the cRIO before the cRIO could process the image itself.
