A pretty nice tool I found. It works pretty easy and simple - it shuts all the procedures down that u don't need to play. U just have to push one button to switch to "Gaming Mode" and another button to switch to "Normal Mode".

I don't trust such software with a 10ft cattleprod.
It has Spy/Ad ware written all over it.

Beyond the issue of giving the program quite a lot of power if run under an administrator account; many peoples "adjustments" to improve performance are more often based on old wives tales and supersititions rather then profiler driven experience.
Actually..this works very well...I believe it was SAS_Walker that pointed this out to us some time ago...I've been using it with ZERO Issues..
Actually a nice find..No Adware, no Spybot...
A Simple tool that shuts down un-needed programs that run in the background and simple waste memory...temporarely shut down while you are gaming....
I've been using this Program for the last week it works nicely and speeds up the game but does not prevent lags

Well it can't prevent server-caused lags for sure. But computer are going down to a minimum.

I'll trust Spidey on this one as I'm a silly girl with no technical knowledge
