for all of you who aren't happy the way the PPI is displayed in the game this is what i found and changed on my F-4E radar
this is how it looks unchanged , the PPI has a green background with a serrated edge on top and left and right , this edge problem annoys me a lot and i was never happy with that green background either
so i start looking in to the Avionics.INI but at first i did not know what to look for until i had a conversation with ludo.m54 and pvince , so i checked the Avionics.INI again and found this entrys , GroundClutter , MapBackgroundLevel and MapHighlightLevel and started to change the entrys
that is the original entry
GroundClutter=0.6
MapBackgroundLevel=0.2
MapHighlightLevel=0.6
that is the modified one
GroundClutter=0.8
MapBackgroundLevel=0.001
MapHighlightLevel=0.8
and that is the result , the PPI looks almost like the real one in a F-4E ,and the serrated edge is no longer a problem , i´m more than happy right now finally i got that problem solved
