Hello AVSIM, Firstly, my main problem is that all my aircraft are invisible! I have no idea what caused this, all I have installed are some add-on sceneries and the PMDG NGX. I had done several flights today and when I fired up the sim, I just started getting this and I have no idea why. The only thing I installed between flights was a DiVX codec, but I uninstalled it after I started having issues. Here are my specs: Windows 7 64-bitAMD Phenom II X4 965 3.70GHz Quadcore8gb RAMGeForce GTX480 I attached some pictures for clarification.

Not an expert here, but standard practive would be to find your fsx.cfg file, rename it to something else and have FSX recuid if from scratch and see if that solves your problem. Cheers, - jahman.

Yea, I tried that, unfortunately no luck. Since I only had the PMDG NGX installed I just went ahead and reinstalled and it looks like everything is fine now.

In the Graphics section of FSX.cfg is HighMemFix=1 there. That tweak is suppose to fix invisible/ghost aircraft. Best regards,Jim
