How to Fix Google Chrome High CPU Usage


Google Chrome is one of the most popular browsers in the world. Although this browser uses more memory to provide better performance and security, its CPU usage should still be quite low.

However, sometimes when Chrome starts to lag, the task manager check may show that it is using a higher CPU percentage than normal. This problem is often more the result of your browsing activities than system faults.

So, we have provided the practices you can adopt to reduce the CPU usage of Google Chrome.

Why does Google Chrome have high CPU usage?

Here are the possible reasons why Google Chrome has high CPU usage on your system:

  • Low spec hardware components.
  • Using many tabs, extensions, etc.
  • Problems with GPU or drivers when using hardware acceleration.
  • Malware infection.

How to Fix Google Chrome High CPU Usage?

Below are the possible solutions you can try when your Google Chrome shows high CPU usage.

Check Chrome Task Manager

Google Chrome has a separate task manager to track the resource usage of each tab or activity. Before trying other solutions, check this utility for the responsible activity. Here’s how:

  1. Press Shift + Esc in the Chrome browser.
  2. Click on the CPU column name to sort your activities.
  3. Look at the processes with the maximum CPU usage.

You just need to close those tabs, videos or renderers to fix the problem.

Minimize the number of tabs

Chrome launches separate processes for each active tab, extension, or renderer. Thus, having multiple tabs takes up a significant portion of your system resources. It’s best to use a small number of tabs and close each one if you don’t need them anymore.

Uninstall unnecessary extensions

As we mentioned earlier, your extensions also create separate processes. We recommend disabling or uninstalling all unnecessary extensions.

You can come in chrome://extensions to list all extensions. Disable them to turn them off and click Remove to uninstall them.

Restart Google Chrome

Running Chrome for a long time can start unnecessary background tasks. These activities also use your CPU to run. Restarting Chrome is an easy way to end these tasks. It is best to end Google Chrome processes using task manager and relaunch the application.

Disable Chrome Background Task

Sometimes the task manager shows that Chrome is running even after closing the browser. This happens if the browser settings allow background tasks to run. You should disable this setting if these Chrome processes show high CPU usage. To turn it off,

  1. Walk in chrome://settings/system in Chrome’s address bar.
  2. Disable Keep running apps in the background when Google Chrome is closed.

Free up space

Your system needs enough free storage space to create a swap file or temporary files. If very little space is available on your system drive, your applications are using more CPU processing capacity.

We recommend that you have at least 2 GB of free disk space. You can uninstall unnecessary applications or delete unnecessary files. It’s also a good idea to use disk cleanup tools to free up space.

Update graphics drivers

Buggy graphics drivers cause many application problems when using hardware acceleration. You should always update the drivers to the latest version. We recommend installing them from official websites. But you can also use Device Manager to update them. Here’s how:

  1. Open Run and enter devmgmt.msc.
  2. Develop Screenshot taken.
  3. Right-click on your graphics device and select Update Driver.
  4. Click on Automatically search for drivers.

Enable/disable hardware acceleration

If you have a powerful graphics processor, enabling hardware acceleration takes some of the load off the processor. Your system starts using the GPU to handle graphics-intensive tasks.

But if you have GPU or low-end driver issues, hardware acceleration can freeze your tasks.

So try enabling and disabling hardware acceleration and check what gives the best performance. To change hardware acceleration:

  1. Walk in chrome://settings/system in Chrome’s address bar.
  2. To toggle Use hardware acceleration if available according to your need.hardware acceleration

Reset Chrome Settings

Many users change Chrome settings according to their preferences. But you might have unknowingly customized some settings that increase CPU usage. Your cookies and cache files can also hog CPU processing capacity. You can fix all these issues by resetting Google Chrome settings. Here’s how:

  1. Walk in chrome://settings/resetProfileSettings?origin=userclick on your Chrome address bar.
  2. Click on Reset options.Reset chrome setting

Scan for Malware

There are many malicious scripts that run on or alongside your browsers. They hide behind the browser and use your system resources to keep running. You need to perform a full scan to fix these issues. Do this,

  • Open Run and enter cmd to open the Command Prompt.
  • Dough %ProgramFiles%Windows DefenderMpCmdRun.exe" -Scan -ScanType 2 and press Enter.

You can also use the Chrome Cleanup Tool to scan and remove such malware. Follow the steps below to do so:

  1. Walk in chrome://settings/cleanup on your Chrome address bar.
  2. Click on To find and follow the on-screen instructions.

Reinstall Google Chrome

If the previous methods were of no help, the only thing you can do with Chrome is to update or reinstall it. We recommend that you completely uninstall it and install the latest version. Here are the necessary steps:

  1. Walk in appwiz.cpl on Run.
  2. Find and right-click Google Chrome.
  3. Click on Uninstall.
  4. Walk in %localappdata%google on Run.
  5. Delete the Chromium case.

Now download and install the latest version of Google Chrome from the official site.

Upgrade CPU and RAM

Google Chrome offers high performance, but its high resource usage is the trade-off. You need a high-end PC to perform many resource-intensive tasks on your Chrome browser.

So, if your Google Chrome still has high CPU usage, you should consider upgrading your CPU. It is better to expand your RAM and upgrade to SSD as well.

Use performance enhancement extensions

Most extensions only use your system resources. But some extensions can also optimize the performance of your web browser. They help preload websites or block unnecessary content to improve performance.

You can search for these extensions and use them on Chrome. But make sure to check user comments and reviews before installing.

Use alternative browsers

Google Chrome is one of the most resource-intensive web browsers. If your system does not have enough resources, you can use a low CPU browser. Some browsers like Opera, Vivaldi, UR, etc. use a relatively weak processor compared to Chrome.
