Yeah, I've been rocking that since my system's RAM and video card started doing really odd things (like slurring video performance like it was playing in super slow-mo). Because my system is so old, I found it disabled a bunch of processes that were interfering with certain games and adversely affecting RAM performance. I think I was getting something like a 41% improvement in overall performance in games that with resource heavy usage. Even though ARMA II runs pretty poorly on my system, it runs noticeably smoother when boosted. I find some games don't benefit much from it, yet others (particularly shooters) gained a noticeable improvement. The Thirdwire flight sims scored a slight frame rate improvement for me, but Black Ops didn't, but that could be due to a number of factors (like the first Black Ops being pretty buggy). I think you'll gain more of a noticeable performance increase if you are running an older or lower end system, but it's definitely worth look in. I think Game Booster 3.5 is the current release. Sorry Mac users, no support for you. Man up and buy a PC if you want real gaming.
