I am having a lot of trouble finding dirt runways using FSX as the color difference is very slight. Has some body come up with a fix of setting that would improve this situation?
I for one have not had this issue but you can try using ADE to enhance The look or even change the texture of the runways though you will have to select the individual airports one at a time to change the type landing surface? I am sure there are general texture fixes out there on the web?
I have noticed that I can change the color shade by going to my video card properties and set contrast hue or lightness and has a big effect in fsx.
