FSX3D Corsica, a large scenery pack for X-Plane 12, was recently released by the developer a few weeks ago. This is a comprehensive package that not only covers all five of the island’s airports, but also everything surrounding them. It includes the terrain of Corsica with its own elevation data and orthophotos from Ortho4XP, autogen typical of Corsica, and much more.
The scenery has been specially optimised for X-Plane 12, featuring PBR textures and a good balance between performance and visuals.
The scenery is available from the X-Plane.org Store for around 50 US dollars.
