In all of the screenshots I see, the runway textures are different. The oil/gas stains and the skid marks are much more detailed. What is this from? just individual addon scenery? Also, completely unrelated, does the Flight1 Super 80 have a working FMC?

I use Xgraphics which will let you choose among many different looks. Weathered,cracked ect.Im sure there are some freebie programs in the library also.
