User Test over at the Crymod forums was already impressed with the visuals in Crysis. While checking out some forest photography he decided that to see if he could replicate that look using the CryEngine 2. These are his results.

The images are hard to tell from a real photograph. Those are some of the most photo-realistic graphics I have ever seen. For more work and some jaw dropping hi-res shots check out the his Crymod forum post here. Mad props man.
