Hi Doug,
Interesting this is... I did what you said and it remains the same, Sometimes it also freezes the sim up long enough for it to crash, Just to rule out anything with my system, I tried the same scenario on my second computer which has different specs and the issue is there too, That's also with a fresh P3D and Global Base install.
Do you have any other suggestions? It gets worse if you go outside in a locked spot view and look back at the terrain.
