    Exclamation DirectX kernel driver (dxgkrnl.sys) causing frustrating stuttering in games


    i have an HP laptop, HP Power Pavilion-17 ab305 with i5 7300HQ and GTX 1050 Ti 4GB and i'm experiencing random stutters in almost every game i play. With some searching i found out that the second driver with high latency is the DirectX drive made by windows, The first one is ACPI.sys but after more searching i found out that high latency of this driver would not cause stutter issues but audio issue which i do not experience, so please refrain talking about that driver.

    the laptop is around 3-4 months old and is running the latest drivers by manufacturer. i tried RMAing the laptop once but they just found out that the laptop was overheating while they were stessing it, which i did not experience even when playing for longer periods of time, and then they just ignored my problem and said there was a different problem than what i described.

    Here is what LatencyMon measured while i was once playing Dragon Ball FighterZ (i do not experience frametime spikes in this game though, i get higher latencies when playing different games eg. PUBG. I think the stuttering is due to the rendering system, DBFZ renders the whole map and characters at once so the GPU has to render just the frames but in PUBG you're constantly moving and the map does to render as a whole at once):

    V-st-i-ek — imgbb.com
    V-st-i-ek1 — imgbb.com
    V-st-i-ek2 — imgbb.com

    By the way i have the stats tab too if you need it but i think it's not neccesary.

    I hope i will finally find a FINAL solution for this.

    Re: DirectX kernel driver (dxgkrnl.sys) causing frustrating stuttering in games

    Make sure that BIOS is updated as well as you networking and video drivers.

    dxgkrnl.sys is the Windows DirectX kernel and is considered sacrosanct. It is not the cause.

    Also, make sure that ALL Windows Updates are installed.

    Regards. . .

    yes, i have already updated everything but the issue it still there. also by the way i checked other forums if other people had similiar problem whith only ACPI.sys, no one. then i checked if someone had stutters with dxgkrnl.sys and there are few forum posts about it, but then you could check the images and tell me which other driver/s could be the cause if you would be kind enough, thanks
