It is! RockPaperShotgun did a
technical analysis to see how Crysis 2 was dumbed down to work on Xbox360/PS3.
"As you can see theres absolutely no comparison, the Crysis 2 cardboard box barely featuring a fifth of the parametric mesh generation of its predecessor, unquestionably as a result of the PS3′s weaker OpenMP..... lowered ambient conditions for both AI and NPCs (inevitably as a result of the 360′s eDRAM chip), and a raise in carbon production by over 300%."
"Crysis 1's intention was, if I were to play it three years later, it looks great,'" said Yerli. "And it does, actually, it fulfilled that. But it made it
difficult for entry-level players. So with Crysis 2, we took a different direction, and it backfired a little bit." ~ Crytek CEO
I am assuming to try to get Crysis 2 to be more mainstream both in terms of gameplay and graphics, they had to dumb it down for consoles. We got a DX11 patch as a pat on the back.....
