i use the shader mod- but all seems correct...

I have found that by checking the box Preview direct x 10 in the settings menu of flight sim the switches re-appear and the outside lights are visible. However there is a severe performance degrade when this is selected so I do not want to run the game with this box checked. I have never had to check it for any of your other models such as 747 or md11. Does this need to be checked for the ngx, your manuals also state that:"Turn setting off. DX10 does not significantlyenhance the visual quality of the simulator and it exacts a heavyperformance toll in the simulator."ThanksBarrie Davies

I've been staring at this picture trying to figure out why this is happening. What I see is that any item that has a reflection map on it is not showing, which makes me wonder if this is some kind of driver issue, or graphics card setting, or more simply, a corrupt fsx.cfg. One thing you can try is to backup your fsx.cfg (rename it to fsx.bak or something similar), start FSX, and let it rebuild it. Report back and let me know if this solves your issue.

I have found a way around my problem it's a bit long winded but worked fine. (NB before doing this I disabled anti virus just incase and also right clicked and ran everything as administrator) 1. Uninstall NGX2. Uninstall FSX SP2 using the uninstall in the control panel.3 Find fsx cfg file and delete.4. Start Fsx (now without SP2) allow new cfg file to be built.5. Re install SP2 for fsx.6. Re install NGX. All switches in the VC are now present and correct and the external lighting look brilliant. Thanks Barrie Davies

Had the same problem, solution above worked...Georg

Its the nav lights, switch them to to the top position.
