Also available via in-game autoupdater
CD Projekt RED today issued a patch for The Witcher 2: Assassins of Kings Enhanced Edition, fixing the display of inter-chapter movies in aspect ratios other than 16:9. Also, game saves from Act 2 created on older versions of the game are now compatible with the Enhanced Edition, which fixes the dwarven mechanism in Vergen.
