I checked out Game Booster after hearing some of you mention it in TS...it gives me about 10-15 fps and is totally worth it! Only problem I've had with it is the TS overlay no longer works - is anyone else having this issue, and has anyone figured out how to fix it?
http://www.razerzone.com/gamebooster basically its a launcher that you can use to shutdown un-necessary processes when you start the game and performs other enhancements(memory optimization?). it starts the processes back up when you exit the game. I was surprised at the improvement I got - went from CPU being my FPS bottleneck to mostly Video Card now.
I get MAYBE 5 fps more using it and to be honest I don't really notice it at all. Biggest boost I got was overclocking my video card from 550mhz to 600mhz. (laptop) I think for gamebooster if you have less than 8gb of ram you will notice a difference. 8gb and over it won't do much.
