Reasons for High CPU Usage on Discord

CPU usage is the percentage of processing power used by an app or software on your computer. Discord is a CPU-intensive app, especially when you're in a voice or video call, and it can use up to 80% or more of your CPU resources. High CPU usage can cause various issues, including slow performance, overheating, and even damage to your hardware.

There are several reasons why Discord might be consuming high CPU resources. Here are some of the common ones:

  • Background Processes - Discord has several background processes that can consume CPU resources, including checking for updates, syncing files, and scanning for malware. These processes can run in the background and cause high CPU usage.
  • Discord Settings - Discord has various settings that can affect CPU usage, including voice and video settings, overlay, and hardware acceleration. If these settings are not optimized, they can consume more CPU resources than necessary.
  • Discord bots - Discord bots are third-party programs that can automate various tasks on your Discord server, such as moderating chat, playing music, or displaying information. However, some bots can cause high CPU usage, especially if they have memory leaks or are poorly optimized.
  • Hardware Issues - High CPU usage can also be caused by hardware issues, such as overheating, outdated drivers, or a faulty CPU. If your CPU is running at high temperatures, it can cause the computer to slow down or crash.

After checking for these issues, you can take measures to fix Discord's high CPU usage on Windows 10/11.
