Orbx has released Iceland Mesh for Microsoft Flight Simulator for free.
Created from carefully blended DEM data, Iceland Mesh is a 100% self-contained product with no changes made to the default mesh or any other files. With virtually no noticeable performance impact, each LOD is consistent without any blurring and minimal LOD morphing when flying over Iceland.
Iceland Mesh is compatible with World Update 5: Nordics, released earlier this month.
Below is a selection of screenshots, showcasing Iceland with the upgraded elevation data.
More details are available over on the Orbx website.
