Windows 10: Incredibly high GPU usage in COM Surrogate

The COM Surrogate task in consuming insane amounts of GPU on computer startup. I can end it however then some of the settings stop working and when I delete it the settings menu no longer opens. It is in the System32 folder so I know it is a legitimate file, no idea what could possibly be causing this and&nbs

Cortana & COM Surrogate high CPU usage when Search or Start Menu is opened

Hi Ruth,

Thank you for suggesting these troubleshooting steps. Unfortunately, starting in a Clean Boot did not resolve the issue. I remember that there were some updates available prior to this issue (KB3156421 and KB3152599) and I didn't do any major changes to
the system.

One thing that I forgot to mention in my first post, is that the high CPU usage also sometimes occurs with the "Host Process for Windows Tasks" process too. It mostly happens with COM Surrogate, but this process shows up sometimes too.

Thanks!

 

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.

 

High Gpu Usage by "cssrs.exe" and "dwm.exe"

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues with high GPU usage on your PC, and I certainly appreciate your efforts in trying to resolve the issue by following certain troubleshooting steps.



One of the things that I can suggest is performing a Clean Boot on your PC and see if the issue persists. Refer the article

How to perform a clean boot in Windows



Performing a clean boot will start the computer with minimal set of drivers and programs, to determine whether a background program is causing the issue. Some of the Startup programs will not load after performing a clean boot on the computer.
However, that functionality will return when you reset the computer to start normally after finishing the troubleshooting.



If the GPU usage is normal after performing Clean Boot, then please refer the section
How to determine what is causing the problem after you do a clean boot
to identify the root cause of the issue.



Note: Please refer the section
Reset the computer to start normally after clean boot troubleshooting to boot the computer in to normal mode after troubleshooting



Let us know how it goes.
