Thanks for your replies folks.
Sorry for the delay in responding; I’ve been playing around with various settings to try and find the cause, but so far, no luck. Unfortunately, I can’t pin down an exact time when the problem started so I’m unable to associate it with any alteration I might have made.
My computer has 3.0 GHz Pentium3 processor with 4 GB RAM and NVIDIA GTX 285 video card. OK, I know I’m due for an upgrade, but it has performed well up to now. I am running WinXP sp3, DX9c, and my FSX has patches 1 & 2 applied. I have a 24” LED monitor and normally run at its native resolution of 1920 x 1080. I’ve tried other settings but it doesn’t make any difference.
I’ve been trying to upload some screenshots to illustrate the effect; I’ll have another go:
Did that work? Stroll on; I think I cracked it!
The fact that only some of the planes are affected is strange. If it were only the addons, I might suspect some kind of mod conflict, but it affects the default planes as well. I'm beginning to think that FSX itself has become fundamentally crippled and I might have to reinstall it. I have a lot of mods, so I'm dreading having to do that!
