Windows 10: Change the rendering GPU for Desktop Window Manager to a distinct GPU via the Graphic Settings

There are some applications that do rendering in the past via the GPU Elektron App like Microsoft Teams for example. One could see the usage in Taskmanager for example. Something seems to have changed here with latest Windows Updates or maybe Nvidia GPU Driver update. But the rendering seems now dominantly beeing done by the Windows Desktop Manager and less by the app itself. When watching this in the Taskmanager then i can see that almost all usage time is on the Dektop Window Manager and no longer on the Application itself.Problem i have with that is that in Windows you can attach an appl

Desktop Window Manager(DWM.exe) using high GPU

Hi Hasnat,

Thank you for writing to Microsoft community Forums.

In Windows, desktop composition is performed by Desktop Windows Manager. The way applications display pixels on the screen, it is managed by DWM. When desktop composition is enabled, individual windows no longer draw directly to the screen or primary
display device as they did in previous versions of Windows. Instead, their drawing is redirected to off-screen surfaces in video memory, which are then rendered into a desktop image and presented on the display.

The GPU (NVidia) usage of 35-40% by games is absolutely normal, however at the same time Desktop Windows Manager is using the high percentage of Intel GPU, which isn’t normal and it might be the cause of the low FPS.

I suggest to refer to the suggestions given by Reymichael Ros, dated March 2, 2018 on

Desktop Windows Manager (dwm.exe) load GPU too much.

If the above step doesn’t work, you may try setting the NVidia card to maximum performance and disable Intel graphics adapter to see if it works.

• Right click on desktop and select NVidia Control Panel from the context menu.
  
• Now on the left hand pane expand 3D settings.
  
• Click on Manage 3D settings.
  
• Under Preferred graphics processor, select
  High-performance NVidia processor.
  
• Click on Apply.
  

Before disabling the Intel graphics adapter, I would recommend to create a system restore point. Please refer to the article:
Create a system restore point.

• Press Windows key + R. This will open
  Run. Alternatively, you can go to Start and search for
  Run.
  
• In Run dialog box, type devmgmt.msc and hit enter.
  
• Expand Display adapters.
  
• Now right click on the Intel Graphics drivers and click on
  Disable.
  
• Click on OK.
  
• Reboot the computer and check the frame rate.
  

In case disabling Intel graphics adapter does not work, I would suggest to uninstall the Intel graphics drivers completely and install the latest drivers from the Intel support site.

• Press Windows key + R. This will open
  Run. Alternatively, you can go to Start and search for
  Run.
  
• In Run dialog box, type devmgmt.msc and hit enter.
  
• Expand Display adapters.
  
• Now right click on the Intel Graphics drivers and click on
  Uninstall.
  
• Check the checkbox to delete the drivers from the computer and reboot the computer.
  
• Download and install latest drivers from
  
  Downloads for Intel HD Graphics 630.
  

If none of the above methods works, I would encourage you to provide your feedback and suggestions using the Windows 10 Feedback Hub app, so that the Windows developer team has direct access to it.

Send feedback to Microsoft with Feedback Hub

Hope it helps.

Desktop Windows Manager high GPU usage persists

Several individuals have reported Desktop Window Manager (dwm.exe) using unrealistic amounts of GPU for video playback, gaming, or any high graphics intensive activity. Here is a list of just a few of the many requests for support on this issue:

Example 1

Example 2

Example 3

Example 4

Example 5

It has been a few years now that this problem has been reported, are there any accepted fixes. From what I gather, even those individuals with serious graphics cards are vulnerable to dwm.exe dominating their available GPU. I myself report this issue, even
on games and design software with the settings at a minimum. For example, Java will be using ~45% of the available GPU, whereas dwm.exe takes up the remaining ~55%. As stated previously, the result is the entire system halting, not just the game. The mouse
will take a few seconds to stutter across the screen, and task manager will take 5+ seconds to even appear.

There have been many suggestions and no results. Is that Microsoft's consensus then? Thank you ahead of time.

 

Change selected GPU in Graphic Settings?

But I don't want to change any gpu setting, what I want is something like this, as I seen in many places:





With the Intel HD Graphics as the Power Saving GPU, and in my case the Radeon RX 580 as the High Performance GPU.

But I don't know how to make Windows change this.
