ErikJust: My question is how transfer my saved games from my Witcher 2 Steam version to Witcher 3 GOG version?
Read this:
Importing saves via GoG.com / Galaxy
If players went through the previous Witcher games on the GoG.com platform, their saves should automatically be detected when beginning a new game in The Witcher 3. If, however, the Witcher or Witcher 2 were played on Steam, those save files will need to be manually transferred to a file location that GoG / Galaxy can register.
Steam saves are typically located in:
[Root]: \ Users \ [Username] \ My Documents \ The Witcher 2
Copy these files, then transfer them to whichever drive you have your GoG games installed to, then into the Witcher 3 folder. Typically, this is:
[Root]: \ GoG Games \ The Witcher 3 Wild Hunt
Once the files have been copied, re-load the game and you should see an "Import Witcher 2 Save" when starting a new game.
