Nvidia Optimus GPU Dynamic Switching

Nvidia is once again pushing mixed GPU interaction to the limits.

For a long time computer manufacturers have been trying to find the right balance between performance and power efficiency, especially where it matters the most: battery powered laptops.

While stuffing two graphic cards in laptops is nothing new: a power hungry one offering maximum performance, and a less powerful one offering maxium power savings; it was up to the user to select which one to use according to special power schemes or by toggling a button.
Often, this also meant the user had to log off and on again... which wasn't very user friendly.

With this Nvidia Optimus the principle is the same, but the toggling is made based on the current needs, without any user interaction and without even flickering the screen.

Asus is scheduled to have this system in their laptops (UL50Vf, N61Jv, N71Jv, N82Jv, e U30Jc) soon.

Check the following video (the jerkiness of the video is due to the capture software, in real life it looks as smooth as you'd expect it to be.)
