"You would" if crysis would support Quadcors.
No.

Crysis fully supports Quad Cores...

RLY??

I just run the cpu_benchmark2 with all settings on low (physik particles ... on veryhigh) on 800x600


as you can see it used all four cores but its poorly optimized for quadcores.
When i play games with the Unreal Engine 3 (Bioshock, UT3...) which is fully optimized, all cores are maxed out nearly all the time.
Another thing is that when you play the game, nearly all the time only two cores are used. As you can see above.

That shows low CPU load pretty evenly divided over the cores, and it looks like there is GPU bottlenecking going on, since no core is fully loaded.
Either that or its latancy to keep threads in sync or something (just guessing, dunno how that works)

Had 1 or 2 cores been totally maxed out, while the others had a low load, THEN it would be "poorly optimized", or well, not really, but less fine grained anyhow.

afaik crysis is not being cpu limited.. its being gpu limited..so I wont expect it to max any cpu with current gen video cards. I was however saying that with quad cores and above, you can actually have not one, but two full cores devoted to physics. Another core can do AI, and the audio and other overhead can fit on the last.

I bet I can get alot more phsyics power and performance out of 1-2 of my cores then have my video card "share" its shaders while trying to render video.

Where did you see that? I quasi-remember an article about the threading of crysis and I only recall one thread for physics and it was of a relatively low load level compared to the primary thread.

Jmag, im not talking just crysis.. I'm talking ANY game. Obviously crysis does not utilize the video card for physics.. nor does any game out now, so I was obviously referring to any game made in the future.
