Dropout. Well at some amount of latency it matters but servo systems will tolerate a lot more latency than software step generation will. 50 - 100 uSec of latency on a servo system will do little more than add a little (less than .0002" at normal cutting speeds) noise to the control loop, but the same latency on a system using software step generation will likely cause stalls during rapids.
