For the best results, the mesh must be layered correctly in the simulator's :
Here is why:
The default mesh in FSX and P3D has a resolution of roughly 38 meters (LOD 10) to 76 meters (LOD 9) in most areas. This means the sim draws a triangle every 38 meters. For flat Kansas, that is fine. For the Swiss Alps, it is disastrous. Default mountains look like sad, melted ice cream cones.
: Remote regions that inherently lack dense satellite mapping data (such as Antarctica, Greenland, and northern Russian territories) are safely standardized to an optimized LOD9 (76-meter) tier to avoid data holes.

The upgrade from default to FreeMeshX is most noticeable in remote and mountainous regions. In Africa, Asia, and South America, the default mesh often sits at LOD6 and LOD7. The transition to LOD10 is like cleaning a foggy window. As one reviewer notes, if you fly outside the United States, the difference is "huge" and "adds to the topography" in a way that makes low-level flying far more engaging.
The standard FreeMeshX Global package does not include the USA, because the default US mesh is already LOD10. However, NineTwo Productions offers a separate FreeMeshX USA add‑on that pushes the resolution to an incredible 9 meters (LOD12) for even sharper detail.

So, fire up your sim, disable that default flat earth, and let FreeMeshX 2.0 show you the mountains you have been missing.
FreeMeshX Global 2.0 boasts native compatibility across a wide range of ESP-based simulator platforms:
The consensus among experienced simmers is that . In many comparisons, FreeMeshX has been praised for looking “better and more accurate than Pilot’s mesh” in certain areas, particularly in the Middle East and other regions that payware packages sometimes overlook. As one user put it, “FreeMeshX is a great upgrade to the extent that I wouldn’t bother buying sole mesh products such as FS Global 2010 and FS Genesis.” For the Swiss Alps, it is disastrous
FreeMeshX 2.0 acts as a neutral baseline layer. It is designed to sit perfectly underneath popular regional textures, vector data, and airport scenery packages. Compatibility Across Platforms
In simple terms, a “terrain mesh” is the digital skeleton of the scenery—the set of elevation points that tell the simulator where to put a mountain peak, a valley floor, or a rugged coastline. The default meshes in FSX and P3D vary dramatically in quality. While the United States enjoys a relatively sharp 38‑meter resolution (LOD10), much of the rest of the world is stuck with coarse data ranging from 76 meters up to 300 or even 600 meters per point. This discrepancy is especially jarring in South America, Africa, and Asia, where majestic mountains appear as soft, rounded bumps.

: Unlike high-resolution textures, mesh data generally has a modest performance impact and does not add to the simulator's texture memory footprint.
