I always belived that with triple buffering, the GPU would stop after generating 2 back frames and then wait for a buffer swap, not continue to render new frames in the second back buffer. Apparently I was wrong.
I think mailbox doesn't really feel smooth because the age of each frame presented is fluctuating randomly with every frame, so smooth animations will appear jittery.

A couple pictures would do this good
