Well, I could post some screenies/fraps footage of it maxxed out in the demo if you want (seeing as the full PC version isn't out yet).

It looks similar to the console version (I have the 360 version, but will get the full PC version as well, I'm impatient like that =)), but you get the bonus (if you have the hardware of course) of crystal clear and sharp textures, no jaggies and no pixelation running at your native res. If you have an nVidia card, you get some PhysX stuff, which you will mostly notice during fights as stuff gets knocked around.

Pre-rendered cut scenes are copy pasted (at least in the demo) and look like they are rendered at 1280x720, so they suffer from pixelation and generally in-game looks better than the cut-scenes.
