[Nottingham] nvidia optimus - any OS

[Jason Irwin]

Anyone any experience of using this on any OS?

At the moment I have to force the use of nvidia in the BIOS as optimus
switching does not seem to work (which can't be right).
When I do force the nvidia card, performance is about 1/10th of the
Intel one (Sauerbraten runs at ~20fps rather than 200fps). Which also
can't be right.
This poor performance is consistent between Windows and Kubuntu
(Bumblebee is installed and working).
I updated to the latest drivers in Windows - no change, although the GUI
definitely has all the knobs and buttons for optimus.

So...err...I kinda need to figure out what I'm doing wrong or if this
lappy has a fault.
