Really under rated game, and this is coming from someone who hated the first Infamous.
Rent or look for a cheap copy guys. The gameplay and pacing are superb. Plus the story/endings aren't half bad.
Back to OP, the visuals are the last thing you want to worry about, just enjoy a wonderful game that is Infamous 2.
