... u guys suppose to be the experts, and that is why I posted this one here :-)

what is Highmemfix ???????

Highmemfix is the very first thing that should be added to anyone's FSX cfg. before doing anything! It is not a tweak but a known fix for graphical erros that occur on FSX. It may be that yuor problem is somehting else associated, but the HIGHMEMFIX will address all kinds of issues such as missing aircraft bits and oddities in sceneries. Please add it to your cfg, regardless. Go to your cfg and add this to the [GRAPHICS] section: HIGHMEMFIX=1Cheers.

...just checked my fsx.cfg and HIGHMEMFIX=1 is there.YairBTWI was about to lend in KBNG, on the the downwind I found that the whole Airport is kind of laying on eleveated platu ..another weird thing ...

Sorry to see you have not sorted this out Yair. I have limited experience with sceneries, but unlike some of the guys who seem more interested in giving you advice about being in the wrong forum, I will try to help. Firstly, this is my suggestion and it should help.1: Make a copy of your cfg and place it in a folder on your desktop.2: delete your cfg file in FSX and then restart FSX. Once restarted, start any flight, it doesn't matter which.3: Close down the flight and untick all addon scenery and make them inoperable.4: Close FSX and go to the cfg file and enter the HIGHMEMFIX=1 to the graphics section of your cfg.5: Start FSX and run a flight where you previously had problems. It will now be a question of seeing where the offending culprit is.So follow GHDs recommendation "try unchecking all of your add-on sceneries then adding them back one at a time until you find the offenders." Let us all know how you get on. EDIT: Please post what addons you have, thanks.
