Expensive for an add-on ... Yes, but what work! If I happened to be disappointed with the add-on, it is excellent. Corsica will never seemed so beautiful. Beyond ten airports that are processed here is the visual that I highlight both IFR in VFR. Moreover, the scene was well optimized, with the default scene, I had to limit my display rate target at 14 fps or 13 fps. Now I blithely target to 24 fps. However, I voluntarily limited to 18, which allows me to increase significantly every other render settings. What a pleasure to see the sunset over the Corsican mountains hanging from a microlight over Solenzara (Zara for purists). Good flights to all pilots (real and virtual). Oh, I forgot: It also runs very well with win7.
