I tried it with the content.xml file - no change. And no, i don’t have any texture or scenery mod. What i found is, when i turn on dev mode and disable “airport coloring”, it looks much better (darker). The “coloring” seems to be the (or one) problem, it puts a bright layer of texture (transparent) over runway and taxiways. The question is, why do i have this problem, and others don’t? The “airport coloring” is recommended to be active, i think, so i will usually let it on.
