Hello,
I am not sure...
But insane the Optimus architexture needs the Integrated Card to be on
all the time the NVIDIA is in use (to write to it´s memory).
In my opinion it´s an ugly hardware design.
Or I am wrong ?
Vgaswitcheroo enables switching on my Asus N53jf.
But do so is resulting in thre old screen which isn´t updated any more.
It looks the main Problem is to get the NVIDIA/Nouveau driver writing in
the Intel ?Framebuffer?.
Where is this function located ?
In the Mainboard BIOS, VGA BIOS, Win7 diver ?
And which way the Data took ?
Through sli or PCI ?
How the find the Call...

I hear that some Optimus enabled laptops have some kind of a pre-windows 7
compability mode in the BIOS...
Does anyone have an idea how this is archived on the hardware side???
Its the same as the pre-optimus hw, most of the pre-optimus announced
hw could actually support optimus as well since its mostly a sw soln.
