Yes the old game only ran at 15-20 fps and it wasn't even synced to the clock! This endeavour also added time sync and I chose 20 fps (which makes some missions harder). Wingman shots are delayed by up to a few frames, but the system has a high latency mode that double-sends steering commands over the lossy layer. The weapon commands are at least synced with where the ships fly.
I haven't tried too much in high latency scenarios (mostly LAN) so we will see how well it holds up online
