But fear not, there are effective strategies to reduce Zoom's CPU usage and optimize your virtual meetings.

To tackle the problem of high CPU usage while using Zoom, it's important to understand its root causes. One major reason behind this issue is the reliance on video and audio processing, which puts a significant strain on your computer's resources. By implementing some simple yet powerful techniques, you can alleviate this burden and enjoy smoother video calls. From adjusting video settings and disabling unnecessary features to closing unused applications and updating Zoom to the latest version, taking these steps will help reduce CPU usage during your Zoom meetings.

Optimizing Zoom for Lower CPU Usage

Zoom has become an essential tool for communication, especially in today's remote work and learning environments. However, heavy CPU usage by Zoom can lead to sluggish performance, overheating, and reduced battery life. To overcome these challenges, it's crucial to optimize Zoom settings to minimize CPU usage without compromising on the quality of your meetings. In this article, we will explore various strategies and settings to help you reduce Zoom CPU usage and enhance your overall experience.

1. Update to the Latest Version

Start by ensuring that you have the latest version of the Zoom application installed on your device. Zoom regularly releases updates that include bug fixes, performance improvements, and optimizations. By updating to the latest version, you can take advantage of these enhancements to reduce CPU usage and improve overall stability.

To update Zoom, follow these steps:

  • Open the Zoom application on your device.
  • Click on your profile picture or avatar in the top-right corner of the Zoom window.
  • Select "Check for Updates" from the drop-down menu.
  • If an update is available, follow the on-screen prompts to install it.

Keeping your Zoom application up to date ensures that you have access to the latest features and optimizations, which can lead to improved CPU performance.

2. Adjust Video Settings

Video calls can be resource-intensive, especially if you have a slow or overloaded CPU. By adjusting the video settings, you can reduce the CPU load without compromising on the quality of your video conferences. Here are some video settings you can modify:

a. Disable HD Video

High-definition (HD) video requires more processing power to encode and decode, which can significantly impact CPU usage. If you don't need HD video quality, consider disabling it to reduce the strain on your CPU. To disable HD video in Zoom, follow these steps:

  • Open the Zoom application on your device.
  • Click on the gear icon in the top-right corner to access the settings.
  • In the settings menu, select the "Video" tab.
  • Uncheck the box next to "Enable HD" to disable HD video.

Disabling HD video can significantly reduce CPU usage while still maintaining a clear and smooth video conference experience.

b. Limit Video Frame Rate

Lowering the video frame rate can also help reduce CPU usage during Zoom meetings. By default, Zoom uses a frame rate of 30 frames per second (fps). However, you can lower this value to lessen the CPU load. Here's how:

  • Go to the Zoom settings by clicking on the gear icon in the top-right corner.
  • Navigate to the "Video" tab.
  • Click on the drop-down menu next to "Frame Rate" and select a lower value, such as 15 fps.

Reducing the frame rate can be especially useful if you are experiencing high CPU usage or have an older device with limited processing power. It may slightly reduce the smoothness of the video, but it can significantly improve CPU performance.

3. Optimize Audio Settings

While video calls often consume a significant portion of CPU resources, optimizing audio settings in Zoom can also help reduce CPU usage. Here are some audio-related adjustments you can make:

a. Use Original Sound

Enabling the "Original Sound" feature in Zoom can prevent unnecessary audio processing, leading to lower CPU usage. By default, Zoom applies various audio enhancements and noise suppression algorithms, which can significantly impact CPU performance. To use the original sound in Zoom, follow these steps:

  • During a Zoom meeting, click on the "Turn On Original Sound" button in the top-left corner of the window.
  • A pop-up window will appear with a prompt to enable original sound. Click on the "Turn on original sound" button.

Enabling original sound allows your microphone to transmit the audio without any modifications or processing, resulting in reduced CPU usage.

b. Adjust Audio Quality

Zoom offers different audio quality settings that can affect CPU usage. By adjusting the audio quality, you can find the right balance between CPU performance and audio clarity. To modify the audio quality in Zoom, follow these steps:

  • Access the Zoom settings by clicking on the gear icon in the top-right corner.
  • Go to the "Audio" tab.
  • Click on the drop-down menu next to "Suppress background noise" and select a suitable option.

The lower the audio quality, the lower the CPU usage. However, be mindful that reducing the audio quality too much may result in a reduced overall listening experience.

4. Limit Active Participants

The number of active participants in a Zoom meeting directly affects CPU usage. More participants require more CPU resources to process and transmit their audio and video data. If you are experiencing high CPU usage, consider limiting the number of active participants in your meeting to reduce the strain on your device. Encourage participants to turn off their video or mute their audio when not speaking to conserve CPU resources.

Furthermore, in large meetings or webinars, consider using the "Speaker view" instead of the "Gallery view" to prioritize the active speaker and reduce the CPU load associated with displaying multiple video feeds simultaneously.

Additional Tips to Reduce Zoom CPU Usage

In addition to the settings mentioned above, here are some extra tips to further optimize and reduce Zoom CPU usage:

1. Close Unused Applications

Running multiple applications simultaneously can contribute to increased CPU usage. Close any unnecessary applications or background processes that are not essential for your meeting to free up CPU resources for Zoom.

Additionally, consider disabling or pausing any resource-intensive tasks or applications, such as file downloads or video rendering, to further minimize CPU usage.

2. Use a Wired Internet Connection

Using a stable wired internet connection instead of a wireless connection can help reduce network latency and improve overall video and audio performance. A reliable internet connection can alleviate the strain on your CPU caused by buffering or packet loss during Zoom meetings.

3. Upgrade Your Hardware

If you regularly experience high CPU usage during Zoom meetings, it may be time to consider upgrading your hardware. Upgrading to a faster processor, adding more RAM, or using a dedicated graphics card can significantly improve CPU performance, enabling smoother and more efficient Zoom meetings.

Before making any hardware upgrades, consult with a knowledgeable professional or IT specialist to ensure compatibility with your device.


Reducing Zoom CPU usage is essential to ensure smooth and efficient meetings. By updating to the latest version, adjusting video and audio settings, limiting active participants, and implementing additional optimization tips, you can significantly improve CPU performance and enjoy a seamless Zoom experience. Remember to regularly check for updates and experiment with different settings to find the optimal balance between CPU usage and meeting quality. With these strategies in place, you can enhance your productivity and engagement during Zoom meetings while keeping your system resources in check.
