But isn't much of the illumination pre-generated on the texture bitmaps 
through traditional slow methods? You can do that in POV-Ray too: render the 
scene with a renderer that supports baking, put the resulting bitmap on the 

illumination (see for instance 
http://www.oyonale.com/modeles.php?lang=en&page=54).
Of course what they did in Crysis in much more complex, but I don't think 
that they do GI in real time (though such stuff exists).
Also, CPU-bound rendering can be pretty nifty when it allows real time reuse 
of illumination data, for instance
