Does it help at all? I'm going to try the free version of it to see if it fixes my crashes I have in BFBC2.
I used to like the older versions of game booster but nowadays its ok it doesnt really help that much. Rather do some windows tweaks, use processs lasso, cfos speed etc if you want good improvements
Try GBoost. It shuts down some services and features that Gamebooster misses. Works well for me. http://www.gzero.com/gboost/home.html http://www.youtube.com/watch?v=2udndztVJUs http://www.majorgeeks.com/GBoost_d6725.html
It's funny, because Windows does this stuff automatically anyway. "Gameboosters' do literally nothing. Unless you have a completely crap rig.
They save you shutting down stuff manually, which is one benefit, but not enough to pay for the software, if its free then no harm i suppose.
