Stereo drivers are intended to enable the NVIDIA stereo Control Panel for the support of 3D Glasses. This is a beta driver so there might be a bit of stability issues for you. Then again it has been a long time since NVIDIA released such a driver so it'll make loads of you quite happy.
One big notice here, these drivers originate from Zalman for their new 3D monitors, as such only Anaglyphic Stereo is supported. Anaglyph images are used to provide a stereoscopic 3D effect, when viewed with 2 color glasses (each lens a different color).
With this release we finally see proper Windows Vista support bor both 32- and 64-bit.
Two files are required to use your 3D glasses with any GeForce card. The first is the ForceWare video card drivers (I suggest Forceware 174.74), and the other is the NVIDIA Stereo drivers you can download from this download section.
After installing the video card drivers to update your video card, you will need to install these new Stereo 3D drivers by downloading, unpacking and installing them. You will need to restart your computer one more time. After the 2 files have been installed, go to the display properties, then click Settings, and advanced. Click on the GeForce tab and you will see a menu pop out from the left side. Click on the one that says stereo properties and hit enabled.
This Stereo Beta driver is the latest addition.it's possible you will need to make this registry adjustment to get the drivers to work:
[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NvCplApi\Policies] "ContextUIPolicy"=dword:00000001
We have a discussion thread open on these drivers in our 3D Stereo forums
