How to play MSFS X On Steam Deck!

first: credit to this conversation https://steamcommunity.com/app/314160/discussions/1/3710433402655939574/
and credit to sylvia_zde on his assistance and his own linux guide.

here is the steps:

Use the Proton Version 6.3.8
if on the steam deck, use the launch commands: MANGOHUD=1 PROTON_LOG=1 PROTON_USE_D9VK=1 %command%
if not on the steam deck, use the launch commands: MANGOHUD=1 PROTON_LOG=1 PROTON_USE_WINED3D=1 %command%

this will get the game functioning, on the free flight menu you will encounter a black screen, however the menu is still functional and the options are viewable when moving the cursor over the options.



Hope this helps


All original credit goes to sylvia_zde, i only found that using PROTON_USE_D9VK=1 on steam deck allows the game to be played in gaming mode
