Yes it seems he has edited the texatlas manually, some textures replaced (rocks) but others not (roads).
The bad diffuse is nv_rockcanyondrklod_d.dds for future reference.
I'm looking at FO3's lod too, he made a lot of lod textures there. By looking at the texatlas, I am now quite sure that the overpass and satcom lod meshes are broken somehow, there is nice textures in the texatlas for them, they should not have that ugly whitish appearance. I'll dig them out later and have a look.
