I can only confirm that, all main terminals loads at exactly 8 nm, not less not more. In any case, this problem doesn't have anything to do with this thread, which is related only to buildings missing *entirely*, because something is preventing our software to run, which is not this case.
The compatibility mode shouldn't be touched, meaning it needs to stay without any of the compatibility modes enabled, otherwise it wouldn't just run. And no, running as admin wouldn't make any difference. Again, these things might worth checking, only when trying to understand why the software is not running at all. This isn't the case: if you are seeing buildings, just the loading has been delayed, which means everything is working.
The only possible explanation, is that another addon is clogging Simconnect with so many commands, that our own are received with a delay. It might be worth trying to disable *every* other 3rd party module in DLL.XML and EXE.XML, by setting the <Disable> tag to True, then trying one by one, and see if it makes any difference.
And, I can't see any runway flickering either. The added mesh should prevent this, and I doubt you have a mesh higher that 4.75 m/pixel taking priority over our own.
Note that, as explained already, to get our mesh to display ( there's nothing to "see", it's just flat, but being flat at highres, it should fix any other mesh that might cause the problem ), both mesh-related sliders in the Graphic Settings needs to be set at 100.
