Actually it may seem faster as this forces the OS to use the high res timer. When media player is open or a Macromedia SWF file is open in Internet Explorer the OS switches to the high-resolution timer. Running media player in the background is one of the ways game server ops get more FPS from their servers (theoretically up to 1000 FPS).
Aas far as tweaking setting I feel the TCP Optimizer is better than Cablenut as you can set things based on your connection speed.
EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
