Why Is Discord Using So Much Cpu

Discord, the popular communication platform, has become an essential tool for gamers, online communities, and even businesses. It offers a seamless way to connect with friends, voice chat during gaming sessions, and collaborate with teammates. However, many users have reported experiencing high CPU usage when running Discord, causing frustration and performance issues on their systems. In this article, I will delve deep into the reasons why Discord may be using so much CPU and provide insights on how to tackle this issue.

The Nature of Discord

Before we explore the reasons behind Discord’s CPU usage, it’s important to understand the nature of the application. Discord is built on a combination of technologies, including voice over IP (VoIP), peer-to-peer networking, and real-time data synchronization. These features are essential for ensuring smooth voice communication and low-latency gaming experiences.

Discord’s advanced features, such as screen sharing, video calls, and server synchronization, require significant processing power. Heavy CPU usage is often a trade-off for the high-quality audio and real-time communication that Discord provides. That being said, excessive CPU usage can be a cause for concern, especially for users with lower-end systems.

Possible Causes of High CPU Usage

There are several factors that could contribute to Discord using a substantial amount of CPU resources. Here are some potential causes:

1. Voice and Video Calls

Discord offers high-quality voice and video calling features, but these can be resource-intensive. When in a call, Discord’s audio processing algorithms kick in to enhance the voice quality and reduce background noise. These real-time audio enhancements can increase CPU usage, particularly if you have a large number of people in the call or poor network conditions.

2. Presence and Activity Updates

Discord constantly updates the presence and activity status of its users to provide real-time information about who is online, playing games, or listening to music. This requires frequent API calls and data synchronization, which can contribute to increased CPU usage, especially if you are a member of multiple servers or have a large friends list.

3. Third-Party Integrations and Bots

Discord supports third-party integrations and community-developed bots that enhance its functionality. These integrations can range from music bots and gaming stat trackers to moderation tools and automated announcement systems. However, some poorly optimized or resource-heavy bots may cause Discord to utilize more CPU resources than necessary.

4. Hardware Acceleration

By default, Discord enables hardware acceleration to offload some of the tasks from the CPU to the GPU. While this can improve performance on systems with capable graphics cards, it may result in increased CPU usage on systems with weaker or outdated GPUs.

Steps to Reduce Discord’s CPU Usage

If Discord’s high CPU usage is causing performance problems on your system, there are a few steps you can take to mitigate the issue:

1. Adjust Voice and Video Settings

Under Discord’s settings, navigate to the “Voice & Video” section and experiment with different settings. Lowering the voice and video quality options, disabling noise suppression, and echo cancellation can reduce CPU usage during calls. However, keep in mind that these adjustments may affect call quality.

2. Limit Server Syncing

If you are a member of numerous servers, Discord’s server synchronization feature may be contributing to high CPU usage. Consider disabling server syncing for servers that you are not actively using. To do this, right-click on a server, go to “Privacy Settings,” and toggle off “Include server in Home Page and Server List.”

3. Optimize Third-Party Integrations

If you are using third-party integrations or bots that are causing high CPU usage, consider removing or disabling them temporarily to see if the issue resolves. Contact the developers of the integrations and inquire about any known performance issues or options for optimization.

4. Disable Hardware Acceleration

If you have a lower-end system or are experiencing issues with hardware acceleration, you can disable this feature in Discord settings. Go to the “Appearance” section, scroll down to the “Advanced” section, and toggle off “Hardware Acceleration.”


Discord’s high CPU usage can be attributed to its advanced features, such as voice and video calls, real-time data synchronization, and third-party integrations. While the application’s resource requirements are necessary for providing a seamless communication experience, they can cause performance issues on lower-end systems.

If you are experiencing Discord’s high CPU usage, consider adjusting voice and video settings, limiting server syncing, optimizing third-party integrations, or disabling hardware acceleration. These steps may help alleviate the issue and improve overall system performance while using Discord.
