Discord is a video game-focused voice and chat app that many players are using. But sometimes some users would be scratching their heads as they have no clue why the CPU usage in Discord is running so high. Actually, this has something to do with the settings inside Discord. To help you solve the issue, we’ve gathered some methods in this post.

Before getting started, you should initiate a restart on your PC. Sometimes a simple restart can refresh your system and terminate the programs that are interfering with Discord.

However, if a restart doesn’t work for you, try the fixes below:

  1. Disable hardware acceleration
  2. Turn off voice processing features
  3. Update your device drivers
  4. Reinstall Discord

1. Disable hardware acceleration

Hardware acceleration, according to Discord, can make Discord function smoother when it’s enabled. But it occupies more GPU source, causes rendering problems for some programs and slows down other applications. To check if this is what causes the high CPU problem, try to disable hardware acceleration by following the steps below:

  1. Open the Discord app. In the bottom-left corner, click on the gear icon next to your username to open Settings.
    open Settings in Discord
  2. In the menu on the left, select Voice & Video. Scroll down and find H.264 Hardware Acceleration. Click the slider to disable it (shown in gray with an X symbol).

  3. Then you’ll need to disable hardware acceleration from the advanced settings:
    In the menu on the left, select Advanced. Then click the slider next to Hardware Acceleration to disable it (shown in gray with an X symbol).
    (Note: For users who haven’t downloaded the recent updates, the option Hardware Acceleration would be found from Appearance > ADVANCED section. )

    After the reboot, head to the Task Manager to check if you’re still experiencing high CPU usage in Discord. If your problem persists, try the next fix below.

2. Turn off voice processing features

Echo cancellation and noise reduction in Discord are the two ways to filter the noise in your calls. But they eat up a certain amount of your CPU. Therefore, you can disable these two options when you don’t really need to use them:

  1. Open the Discord app. In the bottom-left corner, click on the gear icon next to your username to open Settings.
  2. In the menu on the left, select Voice & Video. Scroll down to the VOICE PROCESSING sectionThen click the slider next to Echo Cancellation and Noise Reduction to disable these two options (shown in gray with an X symbol).

    After applying the changes, close the window and relaunch Discord. If turning off voice processing doesn’t give you any luck, move on to the next fix.

3. Update your device drivers

A driver is an essential piece of software that lets your system communicate with your hardware. If the device drivers are outdated, it would cause noticeable performance problems. Therefore, when you are experiencing any issues with your programs, you should attempt to update your device drivers. Driver updates can give you a speed boost, fix problems, and sometimes even provide you with completely new features, all for free.

To update your device drivers, you can either do it manually via the Device Manager or head to the manufacturer’s driver download page to download and install the exact drivers for your system. This requires a certain level of computer knowledge and can be a headache if you aren’t tech-savvy. Therefore, we would like to recommend you use an automatic driver updater such as Driver Easy. With Driver Easy, you don’t need to waste your time hunting for driver updates as it will take care of the busy work for you.

  2. On your keyboard, press the Windows + R keys simultaneously to open the Run box.
  3. Type or paste control appwiz.cpl and press Enter.
