Import Witcher 3 savegames from GOG to Steam in Linux Proton

I recently bought Witcher 3: The Wild Hunt on Steam and wanted to import my savegames from the GOG version. In Windows, that's easy: install the Witcher 3 on Steam, boot it up and press continue; your savegames will be there, as they're saved in Users\you\Documents\The Witcher 3 and both games use that location to store their savegames at.

When playing Witcher 3 via Proton... that's different.

Import your savegames

So, here's the steps:

• copy the complete gamesaves directory from your previous Witcher 3 installtion
• remember the Steam ID of the game: 292030
• locate your Steam library. Per default, it's at ~/.steam/ or at ~/.local/share/Steam/
• go to your-steam-library-path/steamapps/compatdata/292030/pfx/drive_c/users/steamuser/My Documents/
• create a directory The Witcher 3
• copy your savegames directory gamesaves to the newly created The Witcher 3 directory

And that's it!

With the next restart of the game, your savegames are ready to load.
