I don't really understand the question. 3D systems do their thing in hardware and drivers - I don't see why they would care (or even know about) what rate the scene is being updated. 120 times per second, they simply show the left eye whatever is in the left buffer, then do the same for the right eye (60 hz per eye). My program just delivers the coordinates for the objects, the hardware takes it from there and splits it into left eye / right eye views. You can even pause my program (frame rate of 0), and the view will be a static scene, but still 3D.

My nVidia 3D Vision system with a 120 hz Samsung monitor does a terrific job at 1920x1200, no matter what rate I update the coordinates. Anything less than 30 fps makes the animation too jerky.
