How to fix Discord high CPU usage in Windows?

Issue: I don't know why, but my Discord uses way too high a CPU for some reason. As a result, if I launch other apps or games using more CPU, my PC almost begins to overheat. Are any solutions available for this?

Solved Answer

While Discord may not be the most widely used VoIP application, it boasts a monthly active user count exceeding 175 million, relying on it for daily text or voice communication. Particularly popular among members of the gaming community, the app's user count continues to increase annually, thanks to its numerous free benefits.

Despite its substantial growth, Discord has not been immune to technical challenges faced by users on a regular basis. Previously, users reported issues such as constant freezing, malfunctioning search features, and difficulties in hearing others when using a microphone for communication.

Discord high CPU usage is yet another problem that some users come across, and it is something that negatively affects their experience. The CPU usage can go up as much as 50%, even when the application is not actively used. Under normal circumstances, it should not increase resource usage by more than a few percent.

Having Discord using high CPU can result in apps starting to crash, especially when used in conjunction with other resource-heavy loaders, such as video games or video editing software. Likewise, computer slowdowns and lag can occur.

To address this issue, you can try several troubleshooting steps that we provide below. For example, clearing Discord's cache files, repairing corrupted files, disabling/enabling hardware acceleration, or reinstalling the app can help most. If you prefer to address Windows issues automatically, we recommend trying FortectMac Washing Machine X9 repair software.

How to fix Discord high CPU usage in Windows?

Fix 1. Close down the Nitro advert playing an animation

This solution involves stopping the Nitro advertisement animation that runs in Discord. This animation can consume significant CPU resources, especially on systems with limited processing power.

  • Open Discord.
  • Locate the Nitro section, usually found in the sidebar of the main window.
  • Click on Nitro to remove the “New” animation.
  • The CPU usage should now go back to normal.

Hardware acceleration in Discord uses your computer's GPU to manage tasks that would typically be processed by the CPU. Disabling it can help lower CPU usage on systems with powerful CPUs but weak GPUs while enabling it can help systems with stronger GPUs.

  • Open Discord.
  • Go to User Settings (the gear icon near your profile picture).
  • Under App settings, scroll down and select Advanced.
  • Find the Hardware Acceleration option.
  • Toggle it off or on, depending on your circumstances.

  • Locate Discord under Apps section.
  • Right-click the app and select End Task.
  • Scroll down and do the same with any other Discord background processes still running.
  • Type %AppData% in Windows search and press Enter.
  • Find the Discord folder, mark it, and press Shift + Del on your keyboard to delete it.
  • Next, type in %LocalAppData% in Windows search and press Enter.
  • Delete the Discord folder the same way
  • Start the app and see if that helped.

Access geo-restricted video content with a VPN

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
