Does Bioshock truly utilize dual-core CPUs?

[Servant of Shodan]

Like the title says, is it multi-thread optimized?
I have read various reviews that briefly say it is, but can find nothing official, nor can I find reviews that show a single core vs. multi-core comparison.
Thoughts?

Yes, it is pretty optimized for multi cores.

it will be a 25-50% performance boost.

Source? I heard it gives considerable benefit too, but where are these numbers from?

All I can say is that it doesn't seem to use my quad core anything like MOHA does.

Same engine. Isn't the engine responsible for passing threads to the OS for the CPUs to utilize?

"Brief", but VERY telling.

Compare the bottom two AMD CPUs - same cache, and going from a single core at 2.4ghz to dual-core at 2.0ghz yields nearly a 50% performance boost? Wow!

Exactly what I was looking for! Thanks, BigHubris!

I feel a little let bumed out that I just bought the single core A64 4000+ even though I have it at 3.0 GHz. Reason I went single core is that I still play games that are well known to have dual-core incompatability issues, even with all the "tricks" one can use to make a second core not really show up...

Oh well, 3.0GHz and SLI 7800GTX should hold me well for the next year or two.

Smooth on an Opty 170 + 7800 GTX at stock. Same video card + Venice 3000 at 2.7GHz isn't as smooth and hangs occasionally while it catches up (although it also gets the med center crash on that system ). Not numbers...but it's noticeable on otherwise very similar computers, even when the single-core CPU is faster.

For the record, the framerate doesn't tell the whole story in this case. My A64 3000+ @2.4GHz runs it beautifully. But it seems to do so by keeping the rendering / game logic threads well fed at the expense of others. With half a dozen enemies running around the framerate doesn't take much of a hit, but sounds start to drop out and the physics thread falls to about five calculations a second.
