Doom III will come quite close to being perfect in realistic graphics. But there goes the money - it barely runs with a computer accelerated with GeForce 3!
Remembering the hellish atmosphere of the first Doom, it will be too frightening to play anyway...
But, yes, graphics are becoming very realistic. Look at GT3. Then the replay. My father walked behind me when I was watching replay from a race in GT3 and asked what TV-channel I was watching. I told him it was a game - and when he looked the screen longer, he then realized.
"But it looked so real when quickly peeked at!"
