Mz CPU Accelerator is an application that automatically changes the priority of the foreground window, by allocating more CPU power to the currently active application (program-game). Automatically de-allocates CPU priority when a new active application is selected. There is also a feature that gives you the power to manage the cores of your processor! These procedures, can lead to an enormous performance gain!
