    Yea I already had most of those optimizations done. Still experienced the latency/dropout issues.

    Thanks for your help though.

    Reducing the dpc latency


    well friends I also tried many things but what I think worked is as follows

    1. I removed all audio and midi drivers from device manager
    2. disabled serial port , parellel port, hpet, and onboard audio
    3. As I was using firewire card (pci via ), I changed the IRQ of pci slot 1 to 4 and pci slot 2 to 9
    4. Disabled all speed step, boost virtualization, hiper threading, power saving in bios
    5. Rebooted the pc.

    Shut down the pc and inserted pci firewire card and then started

    then onwards my dpc latency shown negligible
    later i enabled the onboard audio.. and installed audio midi drivers still all perfect

    According to Focusrite, the "legacy" firewire driver should be used in Vista/Win 7. I don't know if that will affect latency but improves firewire device operation.

    Good for you - you did yer research too on latency and stuff.

    In my experience when you remove the drivers for reinstall
    Use special software tools that hunt out all leftovers.
    Then a good registry cleaner.

    After reinstall - reboot between each driver to settle the order in properly.
    If you have a problem still

    clear computer properly of driver leftovers/registry fluff
    Then install in a different order/reboot between each install

    Still have a problem - use different version drivers.

    Drivers chipset/sound/lan/firewire/wireless/anti virus progs
    - usual culprits

    Quite often in past M/S updates used to affect drivers.
    So you have to be aware of them - till they fix it.
