MSFS Works perfectly for me on Linux through proton on steam, however I would love to have up to date nav data perhaps with a port of the manager or even a manual install (right now I’m manually copying over from my windows install. the manager does work fully through proton, if you manually sim-link MSFS in proton to your local wine c_drive it almost works, however logging in doesn’t work even manually creating a navigraph-desktop xdg launcher, after logging in it gives me a error 500 and the application doesn’t log in ).
Would love to hear if that’s a possibility especially with the steam deck on the horizon.
