Crysis 2 is Horribly CPU Dependent

Hows it scale with more cores?

On the lower end, it has linear scaling i.e. a Quad core will have double the performance of a Dual core, given the same GPU.

It loves hyperthreading (based on how the Core i5 performs) and L3 cache (as apparent from the difference between the Athlon Propus X4 and the Phenom X4).
