I don't know that I'd have made a side by side pc/ps3 comparison like that, because damn. I mean, I know most pcs aren't going to look like that, but it certainly made the ps3 version look like shit.
In all honesty I don't think the PS3 version looks that bad. For one that was a terrible capture with tons of artifacting for all of the footage. If you remember our first video of the PS3 version the frame rate was atrocious. Obviously you're going to have downgraded textures, resolution and lighting, and probably a 30fps cap, but its serviceable. Not everyone is going to be running the game on a GTX 660+ so a low to mid grade PC will probably be very similar to the PS3 version.
