I made some savegames while playing the Witcher 3. Put them in the 'The Witcher 3/gamesaves' folder located in your documents folder.
The game was played on Patch 1.08.3 with all 16 free Dlc´s activated.
Before you move this files to your gamesaves folder you should make some manual saves of your current gamesave,
it might be possible that they will be replaced with new auto-saves while loading and playing the new gamesaves.
