How to use a CoD4 FPS Config (PC)

FPS Config- http://www.mediafire.com/?q0k8d5q0u74... /exec fps.cfg 5 likes for next tutorial on movie configs and skies? Also, does the mic quality get on anyone's nerves? I sacrifice mic quality for vid quality, but I can make my voice sound better at the expense of worse vid quality and longer render time. Give me feedback on this, as it is my first tutorial.
