    Disable POWERMIZER
    What this hack does is basically force NVidia's Powermizer feature to be disabled when the notebook is plugged in, and yet continue to save power when on battery.
    The jerky aero performance can be attributed to powermizer engaging even when the notebook is plugged in, and aero for some reason does not disengage this.
    Powermizer downclocks the GPU automatically in vista to 100MHZ to save power, and this is why aero runs slowly. After I changed the registry setting below, aero works as expected ! !
    Performs flawlessly on a DV2622CA Pavillion Notebook running Vista Biz SP1

    On Vista change the registry key PerfLevelSrc from x'3333' to x'3322' with regedit. This forces the GPU to run at max when plugged in, but allows powermizer to still work with batteries.

    x'2222' will keep GPU at max on batteries or mains.

    The registry key is found in:
    \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{**unique to you for nvidia**}\0000\PerfLevelSrc

    Hopefully NVIDIA remedies the problems with powermizer in Vista in its drivers soon!

    Thanks colinzim. Work very well with my HP Pavillion dv6000. I have been sluggish flip 3d response from my laptop for over a year now.
