GoG.com has announced that its version of The Witcher 2: Assassin's of Kings Digital Premium Edition will be the only version to ship without any sort of digital rights management. In a press release, managing director Guillaume Rambourg noted that, "DRM is not an effective way to combat piracy," adding that user experience has always been his company's "main concern." Of course, it's also worth noting that developer CD Projekt owns GoG.com, so it's understandable its version would receive a few perks.

If your main concern is to play The Witcher 2 without jumping through extra hoops, it looks like GoG.com is the way to go.
