War with respect to a function of this product, or more precisely, the routes with DB tracks, initially skeptical because my old system (Athlon64 3500.2 GB RAM, Radeon 5750) is not nearly the system requirements erfüllt.Beim 1.Start the game-PT with Karwendel DB I-Tracks was taught a lesson luckily, during loading of the tasks so far no problems have an average of 20 images per second. The graphics are absolutely great, almost photorealistic, thought personally not so much that you can still can get out of the old MSTS. Installation of addons (main program I already had on my plate) takes a little, but it is indeed rewarded ;-) Hope so to have one or the other Train Always like me facilitates the purchase decision.
