mmm, yes. depends on size and complexity of both. but comparing lod-terrain and a patch mesh with both the same amount of faces, is there a better and a worse?
Like if I could use both for the same goal, is there one to prefer?
I dont know, but I dont think there is a hude performance difference.
The biggest difference is in the cituations they are most easy to work with...Like you'll plobably be better off using LOD for a bib open landscape, and patch mesh for steep cliff sides.
