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.
Your original statement was that games were required to run at 120 fps with 3D Vision ON for it to work correctly, with an what I interpreted to be an implication that it had to match the 120Hz refresh rate of the 3D monitor. And I refuted that statement by saying that the game did not have to run at 120 fps with 3D Vision in order for the correct image to get to the correct eye. No where did I say that you didn't need good performance for 3D. Just that it doesn't have to run at a frame per monitor refresh for it to work correctly. If that wasn't your original meaning then I misinterpreted, but my point still stands that you do not need games to run at 120fps in 3D Vision for you to get the correct 3D effect.
