The Witcher 2 Xbox 360 vs. PC comparison video offers you a side by side comparison between the Xbox 360 version of The Witcher 2: Assassins of Kings Enhanced Edition and the PC version of The Witcher 2: Assassins of Kings.
We set the video settings on the PC to the highest, which is on 'Ultra Specs' and we did not change the levels on brightness or gamma. On the Xbox 360, we installed the game and ran it on 1080p with the default brightness/gamma levels. Take it from me, there were no alterations to make one look better than the other one. See for yourself the differences and similarities between the two platforms and leave a comment below letting us know which platform you think looks better.
