aerosoft wonderful madeira mesh

I just got this scenery working, and it's great, considering how old it is, but I have one question...If you look at the land past RW5, or at the islands to the SW, their meshes are blocky and indistinct, and they form big triangles poking out of the water. If I move closer, they pop into focus at close range. Once they do come into focus, they look fantastic, but is there any way to increase the level of detail that I see from farther away without having this annoying, pop-up terraforming effect?thanks
