Ars Technica: "A different kind of Rapture."
Side by side DX9 vs DX10 screenshots. Besides some volumetric fog effects, I see almost no difference.
Minimum specs are a core 2 duo! Definitely going to be waiting for the buff...
Also, X360 timing attack successful. Downgrade any 360 back to a vulnerable kernel even after the internal fuse has been blown.
