The day we'll have photorealistic environments rendered on-the-fly will be
a very great one, but it isn't coming anytime soon. Don't be fooled by the
hype: I've seen many nVidia and Ati demos that had showed promising
results but they have yet to do any of that in games. It will be another 5
years (imho) before we see anything resembling photorealistic quality in
realtime.

Just my opinion though, maybe they actually did it ...
