I tried it during a free weekend. Understand that I'm running 8GB (for now) which is bare minimum for DCS, if not actually below. I could get it to load, most of time time; and run, most of the time, with one aircraft on the map. My impression was that it's just more sand. On the other hand, it will be the go to map for F/A-18 and Tomcat types, more than likely, as it is a global hot spot. For me, though, Caucasus it is. Plenty of, I perceive, more varied terrain, plus a map that runs fairly well.
Personally, I'll wait for a sale, and spend on any good planes to come by instead. It was interesting, but in the end, it's just sand and water with a few admittedly pretty, cities interspersed.
