As explained before - also for xLODGen - the initial settings are sane defaults, however recommendations can not be given because every load order, hardware and personal preference is different.
Use low, medium or high wizard mode. Advanced settings are for advanced users that have read the manual so they can generate with different settings themselves in order to compare results.
On a follow up do you recommend any specific LOD ranges and multipliers for DynDoLod? I am using BethINI and usually just go with their preset "ultra" But for you personally what do you find is the ideal object lod distance and multiplier?
Also I seem to get some subtle shimmering on the whiterun stone walls around maybe at the level 4 lod? I've done a bit of reading and can't really find an expansion, some people suggest fov, AF being too high or z-fighting.
