There is a workaround to play games using 3D anaglyph glasses using an NVidia Card (since series 7 for desktops and series 8 for notebooks according to my lousy research on NVidia website).

You need Windows Vista 32 or 64 bits (I use 64), a NVidia Card (7 series and up for desktop or 8 series and up for notebooks) and anaglyph glasses, A.K.A. 3D Glasses, A.K.A Red and Blue glasses.

1. Go to www.nvidia.com
2. Click on Download Driver>Download Driver
3. Click on Beta and Archived Drivers
4. Choose from the dropdowns: Geforce, your series, your model, your Windows Vista version (32 or 64 bits).
5. Click Search
6. Click in the list: driver version 185.85
7. Click Download

8. Repeat steps 1, 2 and 3.
9. Choose from the dropdowns: 3D Vision, 3D Vision, 3D vision driver, your Windows Vista version (32 or 64 bits)
10. Click Search
11. Click in the list: driver version 185.85
12. Click Download

After that you have to install first the GeForce driver, than the 3D Vision Driver. The system will boot after each installation.
Now, when you open the NVidia Control Panel you will see this page:

Click on Test stereoscopic 3D...
Then Launch Test Application

After that the process is self explanatory, the program will ask you if you have the NVidia 3D glasses, you answer no, than it will configure for anaglyph glasses.

I've played GTA Vice City, Need For Speed Most Wanted, H.A.W.X. and others and they look pretty cool in 3D. Even though the anaglyph glasses get in the way of the colors, after a few minutes you can't even remember them anymore.

Windows Vista offers you to update the NVidia Drivers, do not update or it will update to drivers that do not support the anaglyph glasses anymore.
