I just started using Game Booster with IL-2 COD
http://www.iobit.com/gamebooster.html
It does seem to keep me in the game longer but the game still tends to crash out after about 3 consecutive missions in the campaign, (memory leak?) Game Booster shuts down unnecessary Windows services and anything else the user designates through a simple interface or by dropping the game shortcut into the game booster window. When the game is started it automatically shuts down these services. Might help some of you.
