I thought Metropolis Street Racer was impressive visually but have to agree DOA2 needs to be in the vote. I think in Japan there was a later enhanced version on Dreamcast or perhaps I'm remembering wrongly. Certainly a very beautiful game that wouldn't look out of place on more capable hardware like the original xbox or gamecube.
Shenmue I and II were amazing visually too especially I remember looking into the pond to see the fish just outside the family house. So amazing at the time. A real virtual world. I'm trying to remember one of the stand out moments visually of Shenmue II and I guess that's the beginning as you get close to hong kong.I loved the way they prioritised face detail over general scenery.
