Does the Buildings setting affect the number of buildings in the world?

Does this setting in-sim increase or decrease the amount of buildings present in the world? I don’t use PG, so thinking of turning this down. However, in FSX it also reduced airfield/airport buildings - I guess it’s just one setting for all. Thanks.

No this setting has no effect on PG at all, and no effect on density of the buildings since they are derrived from the real world map data provided by OpenStreet Maps.

It only controls the level of detail displayed for a particular building, like doors, windows, AC units, rain gutter and so on …

I altered your title to add more detail for people searching for this question.
