    Question DPC Latency Issue when gaming (cracking audio) dxgkrnl.sys & storport & usbport

    Hello,

    I'm hearing cracking sounds while gaming, I did some investigation and got a LOT of info from older posts on this very forum, so thank you all for that.
    I found that dxgkrnl.sys has 15ms lag, stoport.sys about 3ms, and usbport about 1ms. Here some screenshots:

    Here with latencyMon:

    My computer specs:
    Fresh Install of Windows 8.1
    CPU: AMD FX-9590 @ 4.72GHz
    GPU: 2x AMD MSI R9 390 8G (crossfire)
    RAM: 32GB DDR3 2400Mhz
    PSU: 1000W CoolerMaster Gold
    Mobo: Asus Crosshair Formula-Z
    Storage: SSD 850 Evo Samsung, about 6TB mass HDD storage.

    What I've done so far:
    Updated BIOS,
    Updated audio drivers,
    Updated AHCI drivers / sata drivers,
    Reinstalled GPU drivers (removed with DDU),
    Ran Windows Performance Analyzer (reports same as LatencyMon),

    I'm a noob with this kind of problem, and I'm stuck now, is there any expert here willing to help me here.
