Update at Gamespot
Crysis will feature out-of-the-box 32-bit, 64-bit, DirectX 9, DirectX 10, and multithreading support. The 64-bit version "will bring a performance difference of up to 10 to 15 percent on each thread" compared to the 32-bit version.
The E3 demo was all about DX 9 shader model 2.0--there was no more technology than this
What's interesting is that Yerli told us that if you have Windows Vista and an older DirectX 9 card, you should still see better performance with Windows Vista than Windows XP, even if the hardware remains unchanged. "DirectX 9 on Vista will run faster throughout due to the better device driver model...which is a great thing because just upgrading the operating system on the same rig, you get a better gaming experience,"
The game will run fine on current, single-core CPUs, but it will take advantage of the latest multicore CPUs, as well. Yes, that means Crysis is multithreaded, which means that it can make maximum use out of dual-core systems
