Here is a very good tip, download the 737 without antivirus on, run the installer, when finished reboot pc then start fsx and allow all the gauges etc.

I changed the Texture MAX load to 4096. It still happens for a split second when changing views but not as bad. I'll keep tweaking. If we get a better fix let me know. Thanks!!! FDX706

I have had the same trouble with the NGX. A solution that has worked for me is to go to the FSX settings and under the aircraft tab uncheck the box that says "aircraft casts shadows upon itself." I have had no trouble with the external visuals since. thanks Barrie Davies

Hi, Posted already under 'Model disappears' but once again here.I added everything to the FSX.CFG but nothing changed.Tried to uncheck "aircraft casts shadows upon itself" but still no changes.I don't think it's a matter of FPS as I'm having up to 20-25FPS. Pieter-Jan
