No one can say for certain if Crysis 2 will become the same benchmarking standard as the original, but nVidia is taking no chances.
nVidia is taking no chances to the tune of $2 Million.
For that, it will not only want exclusive marketing rights nVidia will also want to make sure that Crysis 2 is stressing the right parts of the graphics card. Cynics would guess severe levels of tessellation and PhysX will become significantly more important to the Crysis 2 development team overnight (even if they, somehow, missed including the right levels over the previous 3 years of development).
