i dont support piracy ! if you invented car name Ford , its piracy invented car Fiat? "its the same" just other company . there always a first in an invention. The others follow or improve. it is the same our world2xplane and osm2xp you dont think ? osm2xp its no free... World2xplane its better and free now but i buy it after if really improve performence with more graphical house and disign. its concurence , Windows or linux .. I do not question maxx-fx but honestly you just made one single basic setting after it's over .. If maxx fx changes the settings automatically from a curve of light and shadow to be met, after hours day or dusk then I would say there is a big positive.
