GMA Booster is controversial, to say the least. Despite it being advertised as working for all 945 chipsets, desktop and mobile variants alike, it seems to actually target and perform on certain chipsets. This hasn't been well documented, but it won't do any hard to try. From personal experience, 945GME doesn't have any performance increase as it already runs at full clock rates, despite many different info from various places, where even Intel doesn't have the same info throughout their site and documentation. But sure, do try it and see if it changes the clock rate and the performance. Also, try playing with multicore on and off, to see which works best for you.
There might be someone with a better insight on source optimizations for that game. I'm not sure which engine version it is though, if 2007 or 2009. -- 9xx SOLDIERS SANS FRONTIERS
