I installed for testings, the version 2.5 and that works with the Thrustmaster T-Flight Hotas-X Joystick on Windows 10 Build 15372. So, I'm now downloading the V3.x again and will try again and will re-test! Regarding the v.2.5, compared to FS-X, the Graphic is much better. The Sim works also much more smooth. The question would be, are the extended functions will work as good as in X-Plane?! The fact is, this Prepar3D Sim is not for entertainment, is for training and introduction/learning! And it's expensive: the pro Version cost 200 bucks while the Pro Plus just as 'little' as 2300.00 bucks! I just was getting the v2.5 Pro Plus from a friend, who's a Flight Instructor and also Chief-Pilot of an Airline, and they use that apps in their real simulator!
