In Data/INI/GameData.ini there is an option:
TerrainLOD = DISABLE ; should be handled by options screen.
This forces the renderer to use HeightMap. There is also a (unused) variation called FlatHeightMap which does various things, like baking blended textures, simplifying the terrain geometry by collapsing flat areas, and a distance based texture LOD.
This feature was presumably buggy and therefore not used, and it does appear buggy when I try it, but some of these features may be interesting.
