Yes, it takes some time to setup, and you will need to generate (via dropdown menu in X-Plane, or download) ground routes (the routes aircraft travel from runway to gate and back) for every airport you want to use it with. You can easily have a few dozen AI planes without losing more than maybe a single frame per second, it's very efficient. It also has autogenerated traffic (as opposed to real life traffic), which is very light on frames. Live traffic doesn't work on the ground, so if you want realistic aircraft movement at a given airport, there's no way around World Traffic 3. It is most certainly better than the free Live Traffic plug-in. 'Live schedules' are not important to me, however some airport activity would be welcome. The Live Traffic program seems to be a very intensive undertaking and many folders, which I am trying to steer away from after coming from MFS and P3D. There are others that post in this forum who, as you, seem to know what they are talking about. Being a relative newcomer to Xplane 11, could you tell me if this program is comparable to the Live Traffic program that I just learned of in a recent post on this forum? I find your posts are very helpful to me on a wide range of topics.
