I couldn't find any posts about this scenery for Slovenia but after seeing Tomaž' screenshots HERE, I'm pretty convinced that this must be at least as good as Mailsoft's Switzerland Pro X, if not better.I don't own this scenery yet, but I would be interested to here from anyone else who has it, re performance, quality etc Screenshot below from Tomaž' screenshots HERE

There is hardly any impact on FPS (seriously, it runs pretty much like default), the scenery is very detailed (if you live there you can probably find your house), beautiful place to fly - I'm from Slovenia, so I fly there a lot. Besides Orbx stuff (PNW,..) it's my main place for GA flying.I don't own Switzerland Pro X so I can't comment on that, maybe somebody who owns both could say more about that.

It will take some time, but definitely worth reading http://simflight.com/2010/03/13/review-ssts-slovenia-for-fsx-part-1 Author of this review also reviews for Avsim from time to time. I guess he will probably also write a review for Avsim after second part is released.Price of the scenery looks high at first glance, but when one considers what he gets for the money - with first upgrade there are 15 airports, airfields and airstrips, 3 of them are sloped runways, two of them extremely demanding - a real bush scenery that's seasonal photo real covered with custom autogen and over 500 custom 3D objects blended in, custom AI traffic with over 60 repaints of real life airplanes that populate the skies.I sincerely think statement "next to being there" on their page is not an overstatement.
