X-Plane 11
X-Plane 11 is the previous generation simulator from Laminar Research. This simulator will run on Linux, as well as Mac and Windows.
Running X-Plane 11
This simulator should be able to run out of the box with minimal problems. There are two options when buying this simulator:
Installing Addons
Installing a lot of addons for X-Plane is quite simple as this game runs natively on Linux. A lot of the installation is the same as Windows.
Installing Windows only Addons
The only way to install addons that will only work on the Windows version of X-Plane, you will need to run X-Plane through Proton.
Using Proton will remove Vulkan support, running the game in OpenGL, which will lead to a performance loss and therefore is not recommended!
Most of these addons can be installed as usual with just a simple drag and drop into the X-Plane folder. However, some developers use their own executable installers, like addons bought from X-Aviation.
These can be installed using Wine, where you will have to select the path to your X-Plane folder.
