High Quality Content by WIKIPEDIA articles! Nvidia Optimus is an optimization technology created by Nvidia to save battery life by automatically switching the power of the graphics processing unit (GPU) off when it is not needed and switching it on when needed again. The technology mainly targets mobile PCs such as notebooks. When the GPU power is off, the driver redirects graphics commands to the integrated graphics chip (e.g. Intel GMA). Currently only Windows 7 is officially supported, however the open source project Bumblebee brings support to Linux.
