    Whatever PD or VM, we got a phenomenon. I tried to open istat when PD was running,and see it's cpu usage of both.
    When the system was idle, istat showed about 10%,and taskmgr in xp showed about less than 5%.
    But when it's busy,like playing dvd, XP's up to almost 100%, istat just closed to 40%.

    It's just because that PD seperate the C2D to the each system?

    But when I used VM, it happend the same thing.Whatever it's Support 2 processors option had been enabled or not.

    Hello ack
    PD creates own virtual processor, what is why cpu usage in Mac OS and XP are different.
