Tcpreplay works fine this way if we don't need a very good time flow sync, as it end being late, dépending on the cpu usage mostly. I didn't notice this issue at first, but this became evident using lag statistics available recently in next, so to keep a good sync between tcpreplay and flightgear, using a core affinity, setting a priority higher and preferably on a not overloaded PC/CPU core makes things better, so we got something like that on linux: | |||

The "-x" option ensure a good time sync over the replay (find yourself the best value for your config :) ), i just need to adjust the time offset for the mp clock, to have replayed planes in sync with my session, considered as "real time" buddys. | |||
