Disabling Core in Mac Pro

[rebelx24]

Hi,
I am attempting to disable processors on my Mac Pro using the processor control panel that was installed as part of the CHUD tools package. However, when I disable even a single one of the four CPUs, the computer starts lagging excessively. Is this supposed to happen? I thought the extra processors kick in when one is too taxed, but what do I know? Any help would be appreciated. Thanks.

Why would you want to disable one of the cores?

Put them to good use! Most of the time I run einstein@home (or SETI) on two cores, and do my usual browsing, email, etc with the other two. When I'm working is a different story though..

Well, thing is, I'm trying to run a game (Myst III: Exile, specifically), and I was getting a lot of audio skipping, and somebody told me that disabling a core might smooth it out. I was just going by what they said.
