I'm wondering what principle this Game Booster works on? I'm a bit timid to try out programs like this. I haven't tried it yet but does this shut down / disable services or simply increase the priority of the target application (akin to selecting high priority in task manager). Any thoughts?
According to their FAQ Game Booster:
Game Booster does not touch your hardware or system settings. It only closes background process and services temporarily, so after a reboot, everything will be normal.
When you choose the processes you like to be closed, next time GB will remember those and they will be shown as checked to be closed.
However the AVG does much more with cleaning registry (always very dangerous).
When you optimize for optimum performance with AVG it even does not allow you to use the Aero (uses ressources) and even it turns off the Windows defender. The AVG in gaming mode turns really a lot of stuff LOL.
When I look at the description there is a huge list of services you really do not need most of the time but which consume memory and processing power.
