Thanks for your answer, but my above idea about this had nothing to do with active zones in traffic data, it was about liveries… supposed they solved - or circumvented - the issue with stutters on group flight by not showing the aircraft, when the livery is missing on the player’s machine ? There have indeed been complaints recently about nametags flying around without aircraft underneath… now suppose the same would affect AI traffic visibility ? the MSFS session does receive the traffic data, but it won’t show the aircraft, because its Ukranian (or whatever) livery tag is unknown on the player’s machine ?
This idea came to mind when I saw this topic. It’s your solution… a giant livery pack could solve it…
