Of course I can deactivate the labels but the SimObjects are gone, regardless of the percentage I chose in the traffic settings of Prepar3D 2.1
Is there anything I do wrong? Or do you have an idea of what I'm speaking? Thanks for any help.
There's nothing wrong with the scenery, you simply must disable the labels.
There's a bug in P3D (which we reported to LM, but it hasn't been fixed yet), that *every* kind of Simobject (ground, boats, static objects, etc.) is labeled, even if the labels are supposed to be for airplanes only. FSX didn't had this problem, the aircraft labels option only turned on labels for aircraft, not everything.
Having the label turned on/off, doesn't have any effect on what you see in the scenery, except the labels of course, which might be annoying, so best turn them off.
