Windows 10: Windows 10's Game Mode limits CPU to 50%

Everything works fine when Game Mode is disabled but when I enable it on anything (browser or game) my CPU gets capped to 50% and won't go above that until I disable GM. My CPU is capped only on the app/game I enabled GM on.


I've had this issue since Game Mode was introduced and I hoped it was just another bug that'll be fixed after a couple updates but that hasn't happened yet, unfortunately.


My system is up to date according to both Windows Update and Intel Driver & Support Assistant.


OS build: 17134.376

CPU: i5-4590

Limiting CPU usage.

Hello world,

I currently updated my windows 10 version 1803, the last major update which asked you all the options of location and such again after the install, on my laptop and after that limiting my CPU usage in advanced power management does not seem to work. Before
the update when I limited CPU usage to 50% in my task manager it never exceeded 50%. Now I try to limit the usage to 50% but still, the processes (games mainly) are able to increase the CPU usage to 100%. Tried different power options, like the default, was
Dell power Manager option, tried it with balanced, but did not work. Is there a fix or do I have to revert the update?

Thank you for your time have a great day.

 

100% CPU Usage after Windows 10 upgrade

Hello Aaron,

Thank you for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

Most of the time, computers only use a small fraction of their CPU power. In fact, many computers use less than 5% of their CPU most of the time. When you open an application, play a video game, or encode media file, the CPU usage will rise or spike temporarily.
Once the CPU intensive process completes, the CPU usage should once again drop down to lower level. Most applications will not use up more than 50% of your CPU for an extended period of time. However, some programs and system processes can use up a large amount
of CPU without you even knowing it. This may happen if a program gets stuck in an infinite loop or encounters an unexpected error.

I suggest you to perform Safe mode and Clean boot procedures on the PC by following the steps below.

Step 1: I suggest you to boot your PC in Safe mode by following the steps from the link below and check if the issue is resolved.

Safe mode is a diagnostic mode that starts your computer with limited drivers necessary to run Windows. The words
Safe Mode appear at the corners of your monitor to identify which Windows mode you are using.

Expand the options to boot into Safe Mode:

Reboot the PC to exit from Safe mode.

To know more about Safe mode, following is an article on
Windows Startup Settings (including safe mode) (Applies to Windows 10 also):

http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-safe-mode

Step 2: If the issue persists, perform Clean boot on your PC by following the steps from the link below and check if the issue is resolved.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue.

I suggest you to perform clean boot by following the steps from the link below and check if the issue is resolved.

You can open the system configuration window in Windows 10:

a. Using run command.

• • Press Windows Key + R keys on the Keyboard.
  • Type msconfig.msc and press Enter.

b. Using Cortana.

• • Press Windows icon key on the keyboard and type msconfig.
    
  • Select the top most search result.
    

Follow the steps from 3 under How to perform a clean boot
for Windows 8.1 and Windows 8 from the link below (The steps for clean boot suggested in the link below for
Windows 8/8.1 is applicable for Windows 10 as well):

https://support.microsoft.com/en-us/kb/929135

Disclaimer: Start the computer in normal mode refer the section,
How to reset the computer to start normally after clean boot troubleshooting
from the link above.

Write to us with the status of the issue on the same post for further assistance. Your reply is most important for us to ensure we assist you accordingly.

Thank you.
