Please advise what might be the problem because when flight is restarted it appears on two screens not all three
What do you mean with this ? Are you running FSX with 3 screens, and just *one* of it doesn't display buildings ? That's something entirely outside our control, neither the scenery or the software the runs it have any information about how many screen you run FSX on.
The only possible explanation is that, since running 3 screen takes more Video Ram than normal, it has been somewhat corrupted or exhausted, due to your usage of a very memory intensive 3rd party airplane products, other sceneries in the area, so there's no VRAM memory left to display the airport buildings on one screen.
Some of the solutions are:
- Lower your settings
- Use DX10 (which saves some memory)
- Use a less memory-hungry airplane
- Lower your AI Traffic settings.
The only setting that might have affect VRAM and MUST be enabled, is the HIGHMEMFIX, which should be 1.
