The Bumblebee PPA has been updated today, and the packages now allow the latest "nvidia-experimental-310" drivers to be used with Bumblebee.

Nvidia GeForce driver 310 is said to "double the performance and dramatically reduce game loading times for those gaming" and it can be installed from the "updates" Ubuntu 12.04 and 12.10 repository. Below you'll find instructions on how to configure Bumblebee to work with nvidia-experimental-310 driver.

Nvidia Optimus is a technology used to increases battery life by switching between two graphics adapters (a low-performance integrated Intel graphics adapter and a high-performance one by Nvidia) within a computer system. Optimus GPU switching is officially only supported on Windows, but it's also unofficially available on Linux thanks to the Bumblebee project.
