Thanks, I ran the program however it did not find duplicates..
Tlittle, just a shot in the dark but you dont have "View Optimizations" checked in addon manager do you? It's in the lower right hand corner next to the Anti-popup and Altitude cull adjustments.
The reason I ask is because I was experimenting with that box checked not long ago to see if it made any performance difference and when flying around KDFW it made mine look like what your screen shots are showing as the ground textures would disappear then come back in. Once I unchecked that box it was back to normal.
The "View Optimizations" check box doesn't do this to the ground textures at other FSDT airports that I own, only at KDFW and I imagine that is just because the ground textures are rendered differently at KDFW that the other FSDT airports.
I opened FSX, "View Optimizations" was unchecked. I tried to check it then looked, same problem. So I put it back as it was unchecked. Thanks anyway!
Virtuali I don't doubt that there might be an AFCAD somewhere since what you say about the runway numbers makes sense. But I just cannot find any other AFCAD? When the scenery loads initally I do see a grey runway WITHOUT the runway numbers, then as it loads the runway numbers come in. ALSO here's yet another possible CLUE - when the DEMO runs out the grey runway stays BUT the runway numbers disappear?
