Crytek has published a video showing the rendering technology used in the CryEngine, more specifically in Crysis 3. While I don’t really dig the artistic choices (I find the overall image to be messy due to the high contrast and not that appealing, aesthetically speaking), the technical side is impressive. I especially like the use displacement mapping and tessellation for the vegetation (by the way, see how great that leaf looks; they got the material completely right). The reflexions visible at 1’52 make me think they also implemented the cone tracing technique, just like Unreal did. On the downside, all the parts with falling water felt unrealistic to me.

Last but not least, Toad Technology! :)
