    FCPX will run in 64 automatically.

    You can check Activity Monitor if you like. The 64 bit tasks will be marked 64 bit.

    In some MBP’s you can speed up the graphics by setting Graphics to Higher Performance in the Energy Saver prefs. This will utilize a faster version of your gpu and 512MB instead of 256MB on the graphics card. This will speed things up, but drain the battery faster.

    One exception I’ve found for forcing a 64-bit boot. If you are running 10.6.8 and a Kona card, you need to run in 64-bit or you’ll get a kernel panic. One of AJA’s engineers sent me this page on the subject:

    There’s a difference between running the OS in 64 bit, and running 64 bit apps on a 32 bit boot.

    You must boot in to 64 bit by holding the 6 and 4 keys on startup. That doc will also tell you how to permanently boot in to 64 bit as well.

    Is there a way to know which version of the kernel (64 or 32) is currently running? Will 32-bit applications see a performance hit when the kernel is in 64 bit?

    The link shows you how, and there’s no hit, but there’s no gain.

    They are limited to the 32bit RAM constraints.
