Obviously glasses are superfluous. The frame rate thing is a straw-man. Why perception of 3D really fails is it allows the director to override your field of depth. Whatever depth you choose to focus it is not up to the physics of your eyes to determine what's sharp or not, instead it was already decided during the shot. This is like someone else changes slightly the dioptries of your contacts at random. Very annoying.
