I've spent the past 10 days tweaking Airport Madness 3D for sharper graphics and better performance. Let me know if things are looking any better for you. Still no Boston Logan airport, but that's hopefully coming in a couple of weeks. Enjoy!
Oh, and I also did the following:
Reduced aircraft tag jitter;
Reduced aircraft motion stutter;
Minor performance and aircraft quality improvements;
Replaced aircraft tug;
Earlier rotation points for B747, B777;
Improved cockpit quality;
Modified Laguardia terminal roof;
Fixed LaGuardia gate jam at west apron;
Reduced likelihood of wrong aircraft panel being selected.
