Initially designed for games, Discord also became a great platform for chatting. However, many users reported that Discord has high CPU usage. This can be a problem and it can cause your applications to slow down.

High CPU usage can also affect other applications, such as games. This is pretty annoying and causes your performance to suffer, but you can fix this issue by following our solutions.

It seems like high CPU usage and low GPU usage are bothering many users. If you feel the same, do not hesitate to check our dedicated guide.

Before discovering what can you do to solve this problem, let’s see why is this happening.

Why is Discord causing high CPU usage?

This could just be an issue with the server, and typically when this happens, it’s up pretty soon after. In this case, we suggest checking the Discord server status.

Our presented problem might occur because Discord is a VoIP (voice over Internet protocol), instant messaging, and digital distribution platform.

Therefore, when Discord is working, it requires more hardware resources including the power of the central processing unit (CPU).

Now, let’s see what you can do if Discord is causing high CPU usage.

What can I do if Discord has a high CPU usage?

1. Turning on or off hardware acceleration

  1. Hit the Windows key, type Discord, then click on the first result.
  2. On the Discord app, go to User Settings (marked as a gear).
  3. On the left pane scroll down to Advanced.
  4. Go to the bottom of the window and click on Hardware acceleration.
  5. Click on the Okay button.
Note icon
Hardware acceleration should be ON, as the graphics card will take over a part of the performance. As a result, the processor is relieved.

Many users noticed that having it on was actually causing high CPU usage in Discord, and by turning it off, the problem was fixed.

So, if your hardware acceleration is on, then turning it off could help you. In case this method didn’t work for you, keep on reading.

2. Change the Cores your computer uses

  1. Hit the Windows key, type msconfig into the search bar and hit the Enter key to open System Configuration.
  2. System Configuration should pop up on your screen. Click on the Boot tab.
  3. Click on Advanced Options button.
  4. Untick the box in front of Number of processors.
  5. Click OK and close the windows.

Keep in mind that if this option is unticked, it is telling your laptop not to limit itself to just one core of your processor. By changing this one setting, you can fix Discord’s high CPU usage problems for good.

3. Use a gaming browser

There is a practical way to resolve high CPU usage regarding the Discord app. Namely, you can use the web version to access your account in a dedicated browser for Discord users.

Opera GX is the right place to be when it comes to gaming. You can benefit from Discord or Twitch integration right in the sidebar or stay updated with a new games release calendar.

In addition, you have the GX Control panel that allows the user to control CPU or RAM usage in the browser for better performance and speed.

Hence, this gamer’s browser can guarantee you uninterrupted gaming sessions and complete support for Discord right on the homepage.

4. Download and reinstall a fresh copy of the Discord

Another common fix is to reinstall the app. Downloading a fresh version can resolve the problem, as there may be a problem with your current version. 

This is a frequent solution when you are struggling with other issues. Even when having problems with other apps, you can try reinstalling it, if nothing seems to work.

5. Change the graphics preferences

  1. Use the following keyboard shortcut to open the Windows Settings menu: Windows + I.
  2. Navigate to System.
  3. Stay on the Display page, then scroll down and select Graphics settings from the right window pane.
  4. Select Desktop app under Graphics performance preference and hit the Browse button.
  5. In the pop-up window, find the Discord file, then click on Add.
  6. Click on Options.
  7. Now set the Option/Graphics preference to High performance.
  8. Save and exit, then restart your PC.

Even if your processor is at 100% of its power, it won’t affect the processor itself, and it won’t create any long-lasting damage. The only issue you may have is with the processor overheating.
