Compared to the preview videos we've seen (which other people have noted as being playable on PS3s at shows). And yes, I think the textures and lighting are noticeably less impressive than DkS. Not that DkS looked perfect on consoles, mind - just that there seems to be a lack of ambient lighting in many areas.
Not all areas, either, which is what's weird. Right now I'm in a place with gorgeous god rays and sunset lighting everywhere. The areas I played through last night were flat, ugly, and dull. Inconsistency seems to be a theme.
