How to get the South West when purchased full?

[Gierasimov]

Hi. I was really looking forward yo this terrain. I got DCS: Afghanistan from the e-shop. 

I feel I am missing somethig though...

Looking at Kandahar air base which I understood as being feature complete, I see poor quality of textures which seem to be satellite imaginery from the altitude of 2000 feet, certain buildings within the airbase are there on the textures but not as 3D models and despite all my settings maxed out, the distance between ground clutter being visible or not is so short that it is visible only when taxing but completely gone just tens of feet above ...

Do I need a separate install of DCS: Southwest Afghanistan Map somehow? 

This is the newest DCS map but it's quality seems to be below the free Marianas map and for sure below Syria map.
