Very disappointed with Vista's performance especially gaming!

    Well then you explain why EVERYONE has problem with 32 bit software slowing
    down on 64 bit CPU and OS.

  2. Does "everyone" have that problem?

    Or just folks who have to use version 1.00 64-bit drivers that are
    optimized poorly in comparison with version 3.2738 32-bit drivers?

    I know folks keep saying "drivers, drivers, drivers" with Vista 64,
    but the fact is that virtually all performance-relevant hardware (HD
    controllers, display chipset, etc.) is going to depend hugely on
    device drivers for performance.

    When that layer is not the same (as is inevitably the case, given that
    you can't use the same drivers on both platforms) then it's really
    hard to draw conclusions based on the applications.

    There are two ways around this:

    1) Use a test benchmark that isn't affected by drivers

    2) Compare 32-bit apps on 32-bit and 64-bit platforms

    If you do (2), and the 64-bit platform is slower, then you're either
    looking at inefficiencies of running 32-bit code on a 64-bit OS (as
    you assert) or you're looking at driver issues (as I suggest).

    You can then test the 64-bit version of the app on the 64-bit OS and
    compare that with the 32-bit app on the 32-bit OS. Again, if the
    64-bit app is slower, it suggests either drivers (as I suggest) or
    that the app vendor has written a slower 64-bit version of the app
    than their 32-bit version (unlikely, but possible due to the same
    reasons that "young" 64-bit drivers may be slower than mature 32-bit
    drivers). One may then ask; why bother with 64-bit right now?

    If the 64-bit app is way faster than the 32-bit app on either
    platform, then it's either a better-implimented app, or there really
    is a drastic benefit to 64-bit computing and running 32-bit apps on a
    64-bit app is a waste of 64-bit potential.

    Whichever way you slice it, you always have at least 2 variables
    meshed together - and that makes comparisons difficult to interpret.
