100ms is just fine for me, I think. I don't know how much the console driver or a GUI layer adds. > The system can do better timing but the 100 Hz (or so) screen refresh is > the limit.

Run your update loop > at 100Hz and you will be fine Is there an "official" program that displays the time of the ntpd process? Or is one supposed to get time for uses like this from the system clock? Not that I think it makes a difference with 100ms accuracy, but as a matter of principle it would interest me. /ralph _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
