Obviously the new Macbook Pros do not require a reboot to switch between graphics cards while the previous generation, the one which had two graphics cards made by the same company, requires a login/logout.
The case made for the necessity of this login/logout has been the need for the WindowServer process to be relaunched, and to overcome this, WindowServer would need to be rewritten. Obviously that didn't happen.
Further, if random Nvidia insiders are to be believed, this wasn't done using Optimus technology by Nvidia, but rather by Apple... so...
How do you suppose they pulled that off?
