Patch 1.5 has been released today. It focuses mainly on removing the troublesome DRM (Digital Rights Management), allowing you to play the game without the disc, while providing many additional hours of fun thanks to five new adventures created by the fan community.
Note: Unlike previous patches, this patch is not cumulative and assumes that you are patching a Patch 1.4 of the game.
The Witcher Patch is the next stage of The Witcher (PC)'s life, and is also a means of expressing our thanks to the modding community for their hard work ion creating the adventures. The update will also be included in forthcoming The Witcher: Enhanced Edition Director's Cut; more info on that product will be released shortly.
