A Witcher 3 Patch is coming tomorrow, August 30th, to coincide with the release of the Game of the Year Edition of the game. This version will come with the patch pre-loaded, so these new players won’t need to install it.
Gamers with older copies will want to install version 1.3 of The Witcher 3, as it brings about some changes. The character Dwarf banker Vimme Vivaldi will be “sporting a fresh look”, which we don’t know yet if it will be just aesthetic. The update also fixes a bug in the quest “Without a Trace” where sometimes two enemies are impossible to defeat.
There are also various GUI fixes in this Witcher 3 patch. The full list of changes can be seen on this PDF.
