Umberto,
I am running FSX in the DX10 mode. When I turn onto C5 taxi way I will see these triangle shapes on the taxi way. If I hit them I will crash, and if I just nick them the plane will make a dip like it hit a bump. I have attached a .gif file of what I am talking about. I get the same effect in DX9 as in DX10. Can You help me out? Note: I have uninstalled LAX and re installed it with the same issue. The KLAX airport is for FSX and DX compatible.
Thanking you in advance,
Les H
