Continuing their support for their 2007 RPG, CD Projekt have released yet another patch for The Witcher: Enhanced Edition. In case the significant improvements of the enhanced edition weren't enough, the latest patch goes further to remove the game's DRM copy protection, allowing you to play without requiring a disc in the drive.
