Hi all,It would be interesting to know how other users find different packages performing.I did a simple test to define average frame rate with two locations and settings (almost everything maxed out) I use when I fly. However for this purpose no traffic and clear skies.KSEA 34R (default)Cessna (default) 48 fpsPSS A320 39 fpsPSS A330 & A340 both 29 fpsLDS 767 28 fpsPMDG 737 36 fpsEHAM 24 (NL scenery 2.91)Cessna (default) 25 fpsPSS A320 22 fpsPSS A330 & A340 both 19 fpsLDS 767 18 fpsPMDG 737 20 fpsDo you find similar results? And how does new PMDG 747 fit in?As for hardware I am running AMD 64 3200+ and Nvidia 6800 GT. Based on 3dmark05 I suppose it is running ok. http://service.futuremark.com/compare?3dm05=1042374 Best Rgs Perttu

I get about the same as you, there are a few users who are having issues with the 747, I unfortunately am one of them. While everything else runs smooth as silk, even my Flight1 ATR and the Feelthere ERJ. No one can figure out what the problem is, but it's definitely not our systems, but possibly the way we have our video settings configured, although it's hard to imagine that every other addon runs fine except the 747. My PMDG 737 runs great, and my LDS 767 and all the PSS aircraft are by far the smoothest.Jeff
