The idea of Optimus is to use the lower-spec GPU for the general activities |
41 |
and only enable the higher-spec GPU (NVidia) for processes requiring the extra |
42 |
processing power (generally 3D games or rendering). |
43 |
|
44 |
Using bumblebee, you can start an application using "optirun <application>". |
45 |
The application then can use the Nvidia-chip. Other applications will still |
46 |
use the lower-spec GPU. |
