Hey! Speed Hack

The great Speed Hack program: SpeederXP has a special kernel arithmetic that depends on the “linearity-accelerate” technology so it gradually increases the speed of your computer after you adjust your program’s settings for a high speed. The program’s window will allow you to choose between controlling the speed for the whole system and all open windows at once. When you click on the “target“ icon, it will show you a list of all running GUI applications so you can pick which one to control the speed.
