I live in Illinois which is basically flat, but with Xerces color schemes if I zoom out far enough (much further than on your screenshot) I do get 3D terrain view. I'll compare to what I can get if running on my phone and see if it looks better there. Also, the default DEM file isn't terribly detailed, so I would not expect every local hill to show up...
Boris,
Just to let you know that the screenshot shows the maximum zoom-out (not just far enough) that I have been able to do. Is there any "ini" file which defines maximum zoom-out or how far the details could be shown. The real distance from the bottom of the screenshot to the top "vanishing" point is about 3/4 mile - as you can see after this straight line there is nothing? If there are two colors (town zone and forest - for example) painted inside this area that is going to be shown as a mix of jagged blotches. I have changed several different color schemes - no improvements . . .
Thanks again for all your efforts,
BobD
