"Without a doubt we would've liked Crysis 2 to support DX11 at launch, but there are a few advantages to using DX9, the most important of which is that the pool of PC gamers that run somewhat dated hardware will be able to enjoy the game. Three year-old cards like the Radeon HD 4980 and GeForce GTX 285 provide playable performance at 1680x1050 using the Very High quality settings, for example.
Crysis 2 may not be exactly what PC gamers expected, but despite the seemingly console-biased launch, Crytek has proven that it's still possible to create an incredibly good looking game with DirectX 9. Many new DX11-based games have shown the advantages of the newer API, but we're no longer convinced Crysis 2 suffers from its lack of DX11 -- something we never expected to say. "
im happy ive still got a 4870. it works fine for every game including crysis 2!
