I noticed Forest=4, we have this also? Highest in ReadMe was 3. But gonna give that a try for sure! Also if you use LandGeom=2 with VisibilityDistance=3, that would not give the full range 73km? I have used VisibilityDistance=3 with LandGeom=3 after 4.09m. Thank you for posting the conf.ini ..need to try some of those settings.
