rMBP - Intel HD 4000 - Windows 7

Does anyone know if there is a way to manually switch between the dedicated GPU and the integrated graphics while running Windows 7?

Someone wrote softeware for this under OSX, but I was wondering if there was something similar in the Windows world.

Technically the NVIDIA 650m does support Optimus for the intelligent switching, but they have yet to release officially drivers on their download page.

Historically, laptops with switchable graphics 1) aren't supported by mainstream driver releases and 2) utilize their second graphics solution with OEM drivers.

Apple hasn't released any Windows drivers, and the only way to use Windows on a Mac is to use the dedicated. For me, I have Windows solely to game, so that's not a problem.

A notable manufacturer of switchable graphics laptops is Sony. While their machines are far overpriced (more than Apple's), many of them have a dedicated "Power Saver/Performance" switch that can be configured to switch graphics.

Apple isn't using Optimus, they're using their own chip. I think a gmux driver is in development by the community for Linux. Probably not Windows though. Apple should really be more open with these things.
