After getting their hands on a preview copy of The Witcher 2: Assassins of Kings, PCGames.de has discovered that the game allows for four different graphical presets: low, medium, high, and ultra. So, in order to give us a better idea of how the game looks as you move between low and ultra, they've uploaded several comparison screenshots depicting the castle dungeons, a sex scene with Triss (NSFW), an outdoor camp, and more.
Hmm. I've been considering an upgrade to a GTX 560, and seeing these shots makes me even more interested in pricing out NVIDIA's latest offerings.
