Hi,
another little detail. In zfstream.cxx the input buffer for reading

Hi,
thank you. I've keep working a bit on it. The airport ctor doesnt need to

Now it saves a few megabytes by removing unneeded parts from FGRunways

By using those changes and also by using

Maybe add an option to do full length bubble sort each update?Or quicksort,
even.
It should really be that much of a cpu eater, after the clouds are sorted.
It would result in a bit of frame drop on pan around, but flickering would
disappear.
For users with modern system it would improve visuals.

Yon Uriarte has proposed a patch that limits the frame-rate to 60hz

As I understand it, if you limit

of
maximum display lists to compile each frames, and we could use more
aggressive values until the scenery is displayed. Just a thought.
