OK i'm back again,
I double checked map settings in skyrim.ini and also in the custom.ini and the values are correct, so i don't use uLockedObjectMapLOD=32.
I deleted all logs before regen.
I regened lod with ultra, dynamic lod and seasons checked
I only generated lods for tamriel without grass cache so it was faster
