Graphics switching without restarting Windowserver?

I wholeheartedly suspect that what they mean is NVIDIA didn't write the actual code, they still used exactly the same process with the frame buffers and that the guys from NVIDIA gave them all the assistance they needed.

Edit : it's 8am in the morning and I was completely wrong...check this article from Gizmodo http://m.gizmodo.com/site?sid=gizmo...tail&section=Allpost&targetId=Gizmodo-5516517

 

Whatever they call it, or whatever Ars Technica may have heard; under the hood it's exactly the same as Optimus. The driverside, that's where the difference is.
If you want to be able to switch graphics without having to restart your windowserver, you will need some framebuffer copying mechanism like Optimus delivers.

On the driver side though, Apple managed to make this a whole lot more pleasant than under Windows because Apple made it. (With assistance of NVIDIA ofcourse) On Windows, NVIDIA was on their own, and Windows Vista/7 is always using some kind of graphics acceleration using Aero. So NVIDIA can't automatically detect when a game is running, or when Aero is doing a backflip. At least not as easily.
