    How do you do a clean install of Windows on this kind of machine? If you factory reset the computer it will have the default Dell drivers again, no?

    Its definitely the killer card.
    I tried doing what you suggested and every driver I tried still gave me the latency.
    I even tried to remove all the killer drivers. I was only after I removed the killer card and installed an intel wifi card did the latency get better.
    However it could have been that Windows was simply reinstalling some bunk killer drivers.
    The strange thing about all of this is that I tried drivers from the same 1535 for the Alienware R4 and the problem still existed.
    This problem does not happen on the Alienware R4.

    I am also going to try the intel GFX driver that was previously suggested.
    The reason I am doing that is because even though getting rid of the killer solves the problem 99%, there still seems to be some occasional issues.

    Make a boot able windows 10 USB with Microsoft's tool, delete all the partitions, make a big one, and install windows.

    Thanks. Will it automatically activate Windows? No need for a serial?

    My 9560 also has latency issue, which are gone by simply disable killer network driver. Are you sure Intel's card don't cause latency issue?

    So, we are talking about standard hardware here, not custom built rigs. What solutions do we know of do decrease the impact of DPC etc?

    This is a really long guide for anyone interested in digging down:

    No, I am not as Wifi and BlueTooth devices are notorious for causing problems like these. Problem is, we need them, especially WiFi. At least I refuse to be tied down by a Ethernet cable in 2017 for anything but a server, a HTPC or similar.

    Don't know if it matters at this point. But, I ended up returning the 9560 due to the DPC latency issue. After two laptops and a ton of trouble shooting, there was no fix for the latency issue while using the onboard audio. It was fine for me using an external audio device. But, when traveling, I not going to bring an external device just so I can do editing.
