Nov 8, 2013: Update from Google’s Peter Birch regarding this problem:
This has been fixed by nVidia in their 331.65 driver update. You can download this new driver here:http://www.nvidia.com/download/driverResults.aspx/68799/en-us
From the release notes (http://us.download.nvidia.com/Windows/331.65/331.65-win8-win7-winvista-desktop-release-notes.pdf):
“[3D Vision]: Games are forced into red/green stereoscopic 3D mode after upgrading
the OS to Windows 8.1 “
A number of you have written to us complaining about Google Earth starting to show “red and blue 3d”, with no way to disable it. The result is something like this:
It’d look pretty neat with proper glasses, but is painful to look at without them.
The challenging part of fixing this is that there is not an option in Google Earth to turn it off. The 3D is generated by NVidia video card drivers, and it must be disabled in there. UsedMonkey.com wrote a brief article on how to resolve this, including the note to disable 3D in the NVidia control panel, as seen here:
Elias, the author of the article, also points out that subsequent updates to the driver will re-enable this feature so be sure to check it each time you have a driver update.
