as stated above the micro stepping rate has nothing to do with the clock freq of the current control circuit.
the micro stepping simply changes the current set point - - -
the mechanical aspects have a big effect - - - - how large is each step current change - -
which causes a larger current level shift and the resulting magnetic fields to pull the rotor into position.
if you can smooth out those changes - - - less noise - - -
