One trick: you have some translucent meshes that are drawn after DOF with out separate translucency, that in the background of the city does not look nice on the window of the skyscrapers. That is simply because the content was not populated back in the day with ability to put the city out of focus in mind. Quick workaround to avoid this content restriction is to simply disable separate translucency with “show SeparateTranslucency” in the console.
