    nvlddmkm.sys and dxgkrnl.sys problems


    The nvlddmkm.sys and dxgkrnl.sys drivers have too high latency in LatencyMon. This is causing lag in games. I’ve tried everything: reinstalling drivers, games, Windows, checked the inside of the computer, dug into Windows settings, but nothing helped. Please help!

    :)

    DPC Latency problem (Storport.sys, nvlddmkm.sys, dxgkrnl.sys, etc.)

    Hi,

    For me those DPCs are originated by the Intel Intel(R) Serial IO GPIO Driver.

    The DPC and ISR graph shows a lot of those DPCs spikes.

    It seems that your driver is outdated (ver 30.100.1816.3 released on April 2018).

    A newer version is available on the Dell Website for your computer model.

    Update this driver and see if it helps.

    DPC Latency problem (Storport.sys, nvlddmkm.sys, dxgkrnl.sys, etc.)

    I tried the driver and it seems to have helped a little bit but I haven’t been able to test it out fully. However, due to other issues, like temperature when gaming, Dell will pick it up tomorrow to fix these issues. I doubt that it will help that much, but what can you do?

    Once I receive the repaired laptop, I will check again! Hopefully they check this issue but I doubt they can fix it..

    nvlddmkm.sys and dxgkrnl.sys problems

    Sys Tool program

    I tried downloading Sys Tool from the TPU home page. Seemed to install Ok but wont run. Just gives me the "has encountered a problem and needs to close" crap, and do I want to send an error report. I'm trying to run it on the system I've got listed in system specs. The MOBO uses the i865 chip set. There's no need to OC this one, other than something to do. Is it just not compatable to begin with and wont work?
