You don't seem to understand what frame times are about. If those frames aren't delivered at the correct rate. This is microstuttering. Frames aren't being pushed out as fast or as slow as needed (which is supposed to be a flat 16.6) Thus the image isn't smooth. You don't have to be having framerate drops to be getting microstuttering.
Look at the panning in my shot, as it stutters along.
