Of course, they'll say whatever they need to say to sell the product, Richard. When Crysis came out, I still remember the argument that the game wasn't actually poorly optimised, like, for instance, what the shader analysis seemed to demonstrate.
No, folks, the game was future-proof! It was made after some of the Crytek folks took a trip on a time travelling machine and saw that in the moderately close future all GPU architectures will be optimised for unnecessarily long shaders and tons of full screen post processing effects piled one on top of another. They saw that and they also saw that it wouldn't be wise to capitalise on hedge funds that had too many housing-related securities; they just remembered the GPU parts of the time trip, tough.
Anyway, regarding the game, I wish their "upgraded" and "physically correct" lighting engine didn't produce that horrible sky explosion effect where the colour of the sky exists only on the very bottom edge of the picture and then immediately fade to a #FFFFFF white (or close to).
