9 Ways to Fix Desktop Window Manager High GPU Usage

9 simple and tested methods to resolve the high GPU usage issue by Desktop Window Manager

Desktop Window Manager (DWM) is a system process that is responsible for rendering every item that is displayed on your Desktop. It is also responsible for menus, system animations, and transparency elements on Windows.

Desktop Window Manager typically uses the onboard graphics card to fulfill all the requirements. Many users have been experiencing high GPU usage by the process even when no demanding apps are running. Moreover, high-end GPUs, which have plenty of processing power, have also been facing the same issues.

Fortunately, some known issues can cause this mayhem on your computer and they are simple and easy to resolve. That being said, before you proceed, it can pay off to learn more about the issue.

What Causes High GPU Usage by DWM? How much is the Normal Usage?

Since DWM high GPU usage is a software-based issue, there can be plenty of underlying issues that can cause the problem to pop up on your computer. That being said, below is the list comprising the most common culprits:

  • Outdated or Corrupt Graphics Driver
  • Outdated Windows Version
  • Outdate Intel Drivers (For PCs Running Intel CPUs)
  • GPU Hardware Acceleration Enabled
  • Misconfigured Nvidia Control Panel Settings
  • Corrupted/Damaged System Files

As mentioned earlier, users have been experiencing GPU usage of more than 70% even when the system is idle, which is not normal. The typical range for DWM to use the GPU fluctuates between 1-3%.

Now that you understand the causes of the issue, keep reading further to resolve them once and for all on your computer.

Now, select available updates by clicking on the checkbox having the ‘Graphics’ prefix/suffix and then click on the ‘Download & Install’ button.

Once the update is complete, restart your PC and check if it has resolved the issue.

3. Run DISM, SFC, and CHKDSK

DISM will renew the cached copy of the operating system files from the Microsoft server. SFC will then use the cached copy to repair the existing system if it is damaged or corrupted. Then, the CHKDSK command will scan the physical bad sectors on the secondary storage of your system. You must execute the commands in the order stated below.

First, head to the Start Menu and type Terminal to perform a search for it. Then, right-click on the ‘Terminal’ tile and select the ‘Run as administrator’ option.

chkdsk /f

After that, press the Y key to schedule the scan to be initiated when you boot up your PC next time.

4. Change Process Status Using Task Manager

One of the known causes of DWM using all the available GPU memory is when the task priority is set as ‘High Priority’. All you need to do is change the task priority to ‘Efficiency Mode’ and you will be good to go. Client Server Runtime (crss.exe) is also a process that is often found hogging GPU memory, you should also make sure to change its task priority as well.

First, either right-click on the Taskbar and then click on the ‘Task Manager’ option. Otherwise, press the Ctrl+Shift+Esc keys together on your keyboard.

Then, make sure you are on the ‘Process’ tab from the left sidebar. After that, search for ‘Desktop Window Manager’ or ‘crss.exe’ processes from the list and right-click on them. Next, click on the ‘Efficiency Mode’ option to proceed. Make sure you do it individually for both processes.

Finally, restart your PC and check if the issue has been resolved.

5. Download Intel Driver & Support Assistant

Many users have been able to resolve the issue by updating drivers for all Intel hardware installed on their PC. Thankfully, instead of manually hunting for each driver, you can simply install Intel assistant which will curate a list of all identified hardware installed on your PC and facilitate a one-click update for all of them.
