It may be a fluke, or this might acually be something that works.

I was reading the forums over at IW and came across this in a post by either Justin or Benny, forgot which.

Out of frustration, I DL'ed it and gave it a try before I went into the game.
The game was Smooth as butter.
As some of you know I have a shitty comp., and have been having some serious lag as of late....so far this has helped.

Give it a try and let me know if it is just me or if it helps anyone else.
