No I'm in DX9. I did finally see some aircraft (2 of them) at Geneva by increasing the airline traffic from 25% to 50%, although Zurich was still empty. I also tried a MS default airport (Toronto) and there were a number of aircraft present even with a setting of 25%. I also tried Aerosoft Hamburg, and there was loads of traffic there (not just static either). So I guess this implies that I need to increase the traffic setting beyond 50% to see a reasonable amount of traffic at FSDreamTeam airports, does this sound right?
Well it depends on a lot of things; namely wheather Mr. B. Rank and the MTX team created a lot of AI schedules for the FSDT airport(s) or NOT. But, as a "rule-of-thumb" they do mention in their manuals that you should set the AI traffic sliders (for Airlines/GA) to between 25% -> 50% in order to see a resonable number of AI aircraft and schedules. However, it also depends on a number of other factors like the day/time/season (at that airport) to which some of the AI would be "enroute" to a destination or coming into the FSDT airport. Also, you'll find that at nights the AI traffic schedules are less at many facilities and so, its NOT a perfect AI world.
Also, if your system can handle it, try it at 70% -> 100% and see if things change to more of your liking. And, you can use the TrafficBoard utility provided to verify all active AI schedules.
