The real problem is that Optimus still sucks on Windows 7. Optimus causes problems for games, problems for nVidia's 3D Vision technology, even problems with PhysX. I could be playing so many games much more smoothly and at higher quality if Optimus would actually work well with games and other nVidia technology. Unfortunately, don't expect good Optimus support on Linux until nVidia gets their Optimus act together on Windows.
