A user on Giant Bomb took these 4 screenshots while playing on X360. Especially the first and second one shows off lighting effects. And in the user's own words:
Screenshot 1 (fireplace)
Screenshot 2 (dark descent)
Screenshot 3 (bridge over water)
Screenshot 4 (village overlook)
The game looks even way better than the screenshots i toke because of the quality of the photos , lightning looks better in game than it shows in these photos i toke , then again i say , the demo did have better lightning , but still ..
