    Dang, thats low.

    @ Musho This is not about hardware it's about drivers. That is what it is checking. If someone has the same hardware but is using a different driver the results could be very different.

    I've tried disabling hardware one bit at a time and nothing changed. Maybe it's a combination of drivers.

    I might just try a fresh install and load hardware one bit at a time until I find out what's slowing things down.

    What if some hardware just has badly coded drivers?

    More than likely.

    I found a few more tools but they don't help me. PCI Latency Tool 3.1 v2 lets you set the latency priority on the pci bus, but only if you are running xp.


    CEntrance ASIO Latency Test Utility for audio set up.

    Sorry about that! I thought that might be quite useful if it could curb latency bandwidth on a graphic card so that a pci raid card could get more of a look in.

    Anyway, fresh install, no add in cards apart from graphics. Non used features in BIOS disabled. No AV etc.......latency? Around the same. Dang

    If you're doing that, please report back! I have 2x X25-M 80gb on the way, which will join my single one this Monday in raid0. I will do a fresh install, and will run the latency checker the moment I hit the desktop. If it's still high, hardware does have an effect
