Now I don't know where you're flying in Scandinavia, but it seems to me you're using the wrong trees here. I'd expect spruces and pines in these surroundings...
So sorry.. sim makes those calls not GEX
The default tree tiles are a Aces mess than can not be changed or you will have spruce and pine down in places it should never show and the opposite for other trees. The perf issue with trees is the direct cause of that Aces screw up.
If they gave us a way to redefine the trees on the tile and have is show correct automatically we would have done it.. they dont, and the only way that can be fixed is by redesigning the landclass for the entire world and/or default code in the sim, or, design custom scenery BGL files for trees.
We can not redefine default sim behavior as we do not make scenery, just replace the default tiles
as for where I am flying.. The thread title(s) not only specifies the city but the exact airport code
