It was first only obvious with FG-OSG (!) so that I changed back to FG-PLIB some time ago where I did not notice it. Now, since a short time, FG-PLIB catched up with this problem and I have it on both FlightGear branches. I can reduce it (not fix it) by switching AI-manager and AI-traffic off (preferences.xml => "false"). But it is still there and very annoying as FlightGear was running very smooth on my system in 2006. It it much more visible when flying over scenery parts with many objects placed (ie. my Bremen scenery) and more discrete when flying over "unpopulated" terrain. As reported, framerates are allways high on my system (AMD64 3700, NVidia 6600 GT 256 MB). Regards Georg EDDW
