Retested the above. Performed a clean download and install. The '/mnt/data/games/steam/steamapps/common/Two Worlds II' folder appears to be correctly populated with the relevant exe.
However the prefix directory is not being created at all refer '/mnt/data/games/steam/steamapps/compatdata' directory.
On my steam page it does not show the the game can be played via 'Steamplay' notification.
Could there be some issue due to the fact that this game has a native MAC version?
Steam identifies this game as having a native build and therefore does not allow the game to be played via Proton. I do not have the "Runs on this computer via Steam Play" notification next to the game
To resolve this I suggest that the game is set to not have a native linux build.
Hello @JSJoubert, for the time being I'm going to close this issue report as a duplicate of https://github.com/ValveSoftware/steam-for-linux/issues/5638. If the situation is changed for this game, give me a ping and we can re-evaluate.
An error occurred while launching Two Worlds II "(missing executable) : /steam/steamapps/common/Two Worlds II/TwoWorlds2_DX10.exe."
The game runs as if a native game (completely stable) if I create a clean wineprefix and install Steam and run the the DirectX 9 version. I compared the clean install directory against my Steamplay directory and discovered that the relevant game exe's aren't copied into the main "Two Worlds II" folder in the steamplay version.
