I think so. An engine usually cannot move before it has finished the first
iteration (depth 1) and there is often also a delay when it communicates with
the interface. Another lag occurs when playing on the internet, but I think that
most servers compensate for that (ICS does as far as I know).
The delays should be small but in long games the total delay can become
considerable. The only solution is playing with a small increment.
