In case you are not aware, Orbx has just released a free Iceland Mesh which is compatible with the new World Update 5 for Nordics.
The description says the mesh is 100% self-contained with virtually no noticeable performance impact and changes made to the default contents.
Glad to find this enhancement since the Nordics update, not sure if you agree or not, seems a bit below the standard of what the previous updates offered.
