Hey Guys! This is to all you Windows users out there. I've been using this piece of freeware for a couple weeks now, and it really does what it says, with no spyware, malware, or ads. It seems to really smooth out my gameplay on UrT and a number of other games I've tried it with. Here's the details:

"Designed to help optimize your PC for smoother, more responsive game play in the latest PC games with the touch of a button, Game Booster helps achieve the performance edge previously only available to highly technical enthusiasts.
It works by defragmenting game directories, temporarily shutting down background processes, cleaning RAM, and intensifying processor performance. That means you can keep all the features of operating systems ready for when you need them, but turn them off when you are ready to get down to serious business – gaming.
Works compatible with PunkBuster, Cheating-Death, VAC, and any other anti-cheat software."
