When Boost is activated, Razer Cortex suspends processes that your PC doesn’t need to use while game. This frees up memory and CPU power which results in less laggy gameplay and improved frames per second.

Do I need to launch my games from Cortex for Boost to work?

Razer Cortex will activate Boost when any of your games in your library is launched even from your desktop, start menu or a game client like Steam or Origin.
