Hello David, there are a number of well known and reputaded companies in the area of digital audio, video or digital simulation (automotive), just to name a few areas, which are using a standard PC, Linux and the Preempt-RT patch. With latencies down to the single-digit microseconds region. So it is shown that Linux and realtime will work pretty fine here. br Heinz > -----Ursprüngliche Nachricht----- > Von: linux-rt-users-owner@xxxxxxxxxxxxxxx [mailto:linux-rt-users- > owner@xxxxxxxxxxxxxxx] Im Auftrag von David Aldrich > Gesendet: Montag, 8.
