Hi Umberto, I am sure that there are no other airports around
That's not what I've said.
I said that, if you had another airport nearby AND we didn't choose the 3NM distance to load jetways, stuttering (and memory occupation and frame rate too) would have been WORSE, because we would have to load jetways for two airports at the same time.
But the stuttering while loading would have happened earlier, maybe not during "final" approach, but it would have happened nevertheless.
What I was trying to say, there's no way to remove the pause on loading, because that's the way the simulator works: Simobjects are loaded this way, while other scenery files are loaded in the background and in multi-threading, but it's just not possible to do custom jetways other than with Simobjects.
The only thing that we can choose, is WHEN to have the inevitable pause, and that's why we choose the 3NM distance, to be sure it won't be even worse, in case of close airports.
