The idea of Optimus is to use the lower-spec GPU for the general activities and only enable the higher-spec GPU (NVidia) for processes requiring the extra processing power (generally 3D games or rendering). Using bumblebee, you can start an application using "optirun <application>". The application then can use the Nvidia-chip. Other applications will still use the lower-spec GPU. -- Joost
