Even if the game was only running at 60 frames per second or less, it would still shutter at 120Hz (60Hz per eye), and each eye will still only see the image it was intended to see.
Um... when 3D Vision is turned on, and FRAPS says the fps is 45, when I press Ctrl + T to turn 3D Vision off in-game, the fps will shoot up to 75-80 or so. So with 3D Vision enabled, the fps is chopped almost in half compared to 2D. So if the game is running at 70fps with 3D Vision OFF, it will run pretty bad with 3D Vision on (high 30s). I tested it just now in Half-Life 2 so I don't see how what you're saying is correct.

So it seems games need to run at 100fps+ with 3D Vision OFF to prevent drops below 50fps with it on? Because when I press Ctrl + T to turn 3D Vision on, FRAPS fps changes instantly to being almost chopped in half and gameplay starts to get pretty choppy if fps is below 50.
