Acropolis & FSGlobal 2008

[henry]

Have FSDT Las Vegas sitting on a plateau, I understand that installing the two files found in Acropolis (from Avsim) will make the mesh

elevation around this airport less noticeable.

Have FSGlobal 2008 in GS9 FSX which I believe causes this sort of mesh elevation issues & GE.

Is it advisable to install  these two bgl's in FS9, and if so where do they go.

Is this the only FSDT airport affected.

Not checked KLAS in FSX yet.
