Sorry to dig up an older thread, but it is very relevant to an issue I've encountered.
I am using Robert's file, but he has included dynamic lights that, for some reason, are VERY performance heavy. I am not sure why as so many of my other P3D sceneries with dynamic lights are fine. However, when I try to decompile Robert or your files, many of the libraries don't wind up in the resulting BGL with 1.78 of ADE. I notice this behavior in LFPG, RJAA, and others.
I contacted Robert, but he doesn't seem to be making these sceneries any longer.
