GameLauncher first requires that you select the application* and, once selected, if you press the “Launch” button, will quit as many applications as you have running, launch the game, wait patiently until you are finished, then return the applications to your desktop good as new. Less time wasted, more game-play time maximised.
*Note: the application selected does not have to be a game. If you need to maximise processor time for another application of choice - go right ahead.
