Using this tool is quite simple, download and install it. Run the program and click on ‘Switch to Gaming Mode’, it will present you a list of running programs that may not necessary for your games such as antivirus programs etc. You can either select any one from the list or all. Disabling antivirus program is not recommended, if you are not familiar with the game.

After the game finishes, run GameBooster application from the tray and click “Back to Normal Mode” to restart all closed applications. The program (beta) is designed for Windows Vista, XP and Windows 7.
