I recently found an incredible work on Crysis 2 textures, making them far less disgusting and more realistic.
Here is the blog of author with a lot of screens : http://maldotex.blogspot.com/
(remember to click "read more" at the end of each article to see the screens).
And that's the official topic on Crymod : http://www.crymod.com/viewtopic.php?f=277&t=68555
I hope it's compatible with directX 11 :O
Enjoy !
