Method 2: Stop the Nitro Advertisement Animation In the Discord App

There is a little Nitro advertisement animation that plays in the Discord app. This animation can use up a lot of your PC’s resources, leaving behind little processing power for your system.

  • Navigate to the “Nitro” section in the main window’s sidebar.

Once you have removed the ad animation, your CPU usage should go back to normal.

Method 3: Disable Hardware Acceleration

So if you have hardware acceleration enabled, make sure to disable it by following these steps:

  • Open the Discord app on your PC.
  • Click on the cog icon near your profile picture to open “User Settings”.
  • Now select “Advanced” from under “App Settings”.
