The advanced flight simulator X-Plane 11 [Official Website] will release this "holiday season" and it will feature Linux support. You can see their announcement here.
- A completely redesigned, intuitive user interface that makes setting up and editing your flight a breeze.
- Consistently usable 3-D cockpits and stunningly high-resolution exterior models for all included aircraft.
- A new effects engine for lighting, sounds, and explosions.
- Realistic avionics: all planes are IFR-ready right out of the gate.
- Busy, “living” airports with pushback tugs and roaming fuel trucks, able to service both your aircraft and the simulator’s AI planes.
- New buildings & roads to better simulate European cities
- And more!
This version will still use OpenGL, but they are looking into Vulkan for future versions.
It will cost $59.99, as the current purchasing option direct from the developer will give you both X-Plane 10 and 11 in a bundle. Going by how much the current game is on Steam, by itself X-Plane 11 should be half that.
While they don't list Linux on their website specifically for X-Plane 11, they did openly confirm it on their Facebook:
Thanks for sending it in SuperTux.
