Firstly thank you for this wonderful airport add on. I know it started out life in FS9, so its marvellous to see it so good in P3d. (P3dv3.4)
However, the only issue I personally see is that the runway elevation looks slightly off.
The aircraft wheels appear to be below the runway surface slightly, perhaps half a wheel below. Also the yellow runway marker lines are slightly higher than the runway surface. 4096 resolution and 7cm texture is set. Best regards.
I use Orbx Global, Orbx NA LC and Orbx NorCal.
