    What happens if you do a display driver reset with windows key + ctrl + shift + b?

    Nothing. I mean the screen flashes once, but FS performance does not drop like when I do a Windows restart.

    I have some driver issues too here and there. If I use MSI AB my system runs 3D clocks 24/7. If I don’t use msi AB it’ll downclock to normal 2D levels. But then I can’t undervolt my GPU, or overclock my GDDR5X memory.

    Also sometimes when I launch a game it will only boost to 398Mhz lol and it shows 100% GPU utilization. Closing and re-opening the game usually fixes this.

    I just deal with it. If I want to overclock or undervolt my GPU it’ll never downclock to 2D levels because I require MSI AB.


    I’ve reinstalled windows, ran DDU, changed drivers for the GPU. I even changed the settings in MSI AB trying to fix it with absolutely no luck.

    Another thing too, my Clevo GTX1080 is actually a factory overclocked model, so it’ll run 1,647Mhz with 1,847Mhz boost by default and even downclock to 2D low power speeds. But, once I run MSI Afterburner it switches from 1,647mhz default to 1,556Mhz default and forces 3D clock speeds all the time.

    It is very stupid. And I wish there was a fix for this. I wish I could just render a overclock and have 2D clock speeds at the same time.

    Ccc is not installed, using Obsidian software.

    Unlikely to be a display driver issue then.

    After carefully testing I can confirm it is.
    Installed standard Nvidia 441.20 and 441.34 with ddu clean install and both had the same issue which the previous 3 Nvidia drivers had:
    Fire Strike graphics was normal and laptop Gsync worked fine when laptop cold booted, however testing same things after reboot I could see stuttering and FS graphics score dropped from 24000 to 14000 and remained like this until I cold booted again.
    Tried the 5 latest standard drivers, desktop and laptop and all had this bug.

    What I did to fix this is that I ddu unstalled Nvidia driver and installed clevo 431.40 dch driver. After that I tested the laptop after reboot and performance was fine, no stuttering or fs gs drop as seen with standard 441.20 Nvidia driver.
    Just for the sake of science, I did not uninstall clevo 431.40 and instead express installed Nvidia 441.20 dch over it keeping the settings.
    I rebooted, cold booted did everything which triggered the bug before, but did not happen again, performance is fine now and with 441.20 Gsync is slightly smoother than with 431.40.

    I dont know if express installing over clevo 431.40 dch driver or using dch instead of standard fixed it, but it is working fine now.

    Now all what remains is to find a fix for the 8700k microcode issue found both in .25 and .27 clevo BIOS .

    441.40 driver fixed my constant 3D clock speeds. My GTX1080 steps down to 2D levels now.
