See this: [link=http://www.nvidia.com/object/3D_Vision_Main.html]3D Vision[/link]

I have the monitor, graphics card ( Nvidia GT295 ) and glasses setup.

It works great with versions of Realflight, G3, G4, G5.

It is sort of pointless with many other sims that do not render the virtual world in 3D, such as Reflex, Phoenix, etc.
