Personally I think this mod is not really fixing anything it is mealy hiding/reducing the affects of the fundamental problem with how building LOD’s are handled and how building are loaded into the game.
There is no point in making the highest detail LOD available when you select “lowest detail buildings” there is no need to have building popup at close range followed by rapid LOD change until you get the highest LOD close by because building detail only affects the range that the LOD’s are seen rather than effectively just blocking the most detailed LOD’s and thus naturally limiting higher detailed 3d LOD modals, big texture and normal maps being loaded, if you only reduce the LOD range then you still have to load all the big textures and normal maps.
It would also have made more sense that if “flying” other than when one bailed out that the highest detail LOD was not available anyway as that detail is irrelevant >100mph >100ft
