  1. Desktop Window Manager(DWM.exe) using high GPU


    I have asus rog strix scar 2 gl704gw with rtx 2070... Problem started from Day 1.. Having frame drops in fortnite on low setting 90-100 FPS... The only problem i can see is game is using 35-40% Rtx 2070 and the dwm.exe is using 40% intel integrated graphics at the same time...... On idle dwm.exe uses 2-5% intel with ups and downs sometimes goes to 0....Currently viewed all the forms related to this topic with no solution...


    Things i have tried:

    1- set dwm priority to low

    2- turned off scaling for apps

    3- installed nvidia drivers again manually and also from geforce experience.

    4- laptop came with window 1803...updated to 1809 same problem..... Then tried 1709 worked well game used 100% intel hd 630 in game and no dwm problem in that version but nvidia drivers does not support that version for my laptop..... I have came to realize that the problem is in 1803 and 1809 but myn laptop only supports these versions..... I'm stuck plz help.

    5-played with nividia control panel with no solution.

    6-And tried number of options availabe on different forms with no solution.

    :)

    kill dwm.exe windows 10 pro 64bit


    I found this link

    What is dwm.exe and why is it using so much memory?

    With this note: "The steps below only work for Windows Vista and Windows 7. Desktop Windows Manager is not displayed in the Services window on Windows 8 and Windows 10, and therefore cannot be turned off or disabled."

    Desktop Window Manager(DWM.exe) using high GPU

    Desktop Window Manager (DWM.exe) taking up high GPU resources

    Ever since 10/10, the Windows service "Desktop Window Manager" or DWM.exe has been taking up a lot of GPU processing. It can go as high as 12% or more during normal use, but the real problem is that it jumps
    as high as 50% usage during a game, severely reducing my performance. The problem gets worse the more demanding the game I'm playing is. That is, DWM's GPU usage increases with the GPU use of the game I'm playing. Games I could run at max settings at 80-120
    FPS now drop down to 30 or less because this process is taking up a large chunk of my GPU.

    I've been run through the whole gamut of level 1 help desk "cure all" solutions which solved nothing. Looking up the problem online had no solutions. As a service DWM.exe used to be able to be disabled, but
    apparently Win10 no longer allows that. I'm wondering if anyone else has had a similar problem. Nothing major or even minor was changed before the problem manifested, other than update KB4462919 being installed the night before.

    My video drivers have been rolled back, reupdated, un- and reinstalled, I did a system restore to a point before the problem appeared, tried booting with all third party services disabled, and replicated the
    problem with a new test user account. I ran a scan with Malwarebytes and removed a few minor threats. I've tried clean boot.

    Windows 10: Version 1803: Build 17134.345

    Custom-built PC

    Ryzen 1600X 6-core

    16G RAM, DDR4

    NVIDIA GTX 1070ti

    M.2 SSD (boot drive), 2.5" SSD, 2TB HDD

    All drivers are up to date.

    I have a theory. When playing a game, Desktop Window Manager goes as high as it has been, but the game process itself stays very low (0.1% usage). I think that Desktop Window Manager is somehow routing all graphics through itself, which might be a major
    inefficiency.
