Windows 10: Managing the GPU

Hi all,

I don't undetstand how can I manage which program will work with which GPU.
For example :
I've set Firefox in the graphic setting in windows to work on the Intel UHD and same setting are set on the Nvidia control panel.
But, Firefox still appears on the Task Manager on GPU 1 which is my nVidia card.

Any idea how to control this ?

Thank you.

GPU

Hi Michael

Open Device Manager (accessible by right clicking your Start Button)

Expand the Display Adapters section

You should see your GPU listed, along with possibly an integrated graphics option

If that is no listed there:

Boot into BIOS (start your system, then on the manufacturers screen, repeatedly press the appropriate key (usually F2) to enter BIOS

Under System Information, you should find your GPU listed

If you still cannot find the GPU listing, what is the Make and exact Model No. of your PC - that will be printed on a sticker on the bottom casing . ..

 

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.
