its called Razer Cortex. idk if its even worth getting but i really like Dayz and would like to play it without lagging. but here is what the FaQ says............
How does Razer Cortex: Boost work?
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.
