I was going to point out Halo 3, but someone above me just did. Halo 3's campaign graphics set is fairly impressive considering you need to account for 4-player co-op and a lot of stuff on screen at times. Then I was gonna say Ace Combat 6, and someone said that just now too.
So I'm going to say.....Fuzion Frenzy 2. No. Kidding!!!
I'm still a fan of Oblivion's environments. And Fable 2's. Just don't look too closely at character models for either. I also agree with Crackdown, and, of course, the various car games - Forza, PGR, Burnout too. But that's just easier to do.
