How to Fix Discord High CPU Usage on Windows 11: Step-by-Step Troubleshooting Guide

Discord is a popular communication app for gamers and communities, but it can sometimes cause high CPU usage on Windows 11. This can slow down your computer and affect performance.

High CPU usage means your processor is working harder than it should be, which can cause lag and overheating. Fixing this issue helps your system run smoothly and keeps Discord responsive.

This guide will walk you through simple, step-by-step troubleshooting methods to reduce Discord’s CPU usage on your Windows 11 PC. Each step is explained clearly, so even beginners can follow along.

By the end, you’ll know how to optimize Discord and improve your overall computer performance.

Quick Note Before You Begin

Before starting, ensure your Windows 11 is up to date. Sometimes, system updates fix bugs that cause high CPU usage.

Close other heavy programs running in the background, as they may affect Discord’s performance.

Make sure your Discord app is updated to the latest version. Outdated versions can have performance issues.

Step 1: Restart Discord and Your Computer

Sometimes, the simplest fix is the most effective. Restarting Discord and your PC clears temporary glitches causing high CPU usage.

First, right-click the Discord icon in the system tray and select Quit Discord.
Wait a few seconds, then open Discord again.
If the problem persists, restart your computer. This refreshes your system resources and closes stuck processes.

This step helps because sometimes Discord gets stuck in the background using more CPU than necessary.

Step 2: Disable Hardware Acceleration in Discord

Hardware acceleration allows Discord to use your GPU to improve performance, but on some systems, it can cause high CPU usage.

Open Discord and click the Settings (gear icon) at the bottom left.
Scroll down to Advanced under the App Settings section.
Find Hardware Acceleration and toggle it off.
Discord will ask you to restart the app. Click Okay to restart.

Disabling hardware acceleration forces Discord to rely on software rendering, which can lower CPU load on some computers.

Step 3: Clear Discord Cache

Discord stores temporary files called cache which can sometimes get corrupted or too large, causing high CPU usage.

Close Discord completely.
Press Windows + R to open the Run dialog box.
Type %appdata%discordCache and hit Enter.
Select all files in the Cache folder and delete them.
Restart Discord and check if CPU usage improves.

Clearing the cache removes old or corrupted files that might be making Discord work harder than necessary.

Step 4: Disable Unnecessary Discord Features

Some Discord features like animations, GIFs, or overlay can increase CPU usage. Disabling these can help.

Go to Discord Settings (gear icon).
Under Voice & Video, disable Enable Quality of Service High Packet Priority.
Under Text & Images, turn off Automatically play GIFs and Animate Emojis.
In the Overlay section, toggle off Enable in-game overlay.

Reducing these features minimizes background activity and lowers CPU demand.

Step 5: Update Graphics Drivers

Outdated or faulty graphics drivers can cause high CPU usage with Discord, especially if hardware acceleration is enabled.

Press Windows + X and select Device Manager.
Expand Display adapters.
Right-click your graphics card and select Update driver.
Choose Search automatically for drivers.
Follow prompts to install any updates, then restart your computer.

Keeping your graphics drivers current ensures compatibility and smooth performance with apps like Discord.

Step 6: Reinstall Discord

If the problem continues, reinstalling Discord can fix corrupted files or improper settings that cause high CPU usage.

Open Settings from the Start menu.
Click on Apps then Apps & features.
Find Discord in the list, click it, and select Uninstall.
After uninstalling, visit Discord’s official website to download the latest version.
Install Discord and sign in again.

Reinstalling restores Discord to its default state, often resolving hidden issues.

Advanced Option: Use Task Manager to Identify Problem Processes

If you want to dig deeper, Windows Task Manager can show which Discord processes use the most CPU.

Press Ctrl + Shift + Esc to open Task Manager.
Click on the Processes tab.
Look for Discord.exe and check the CPU column.
If you see unusually high CPU usage, right-click and select End task to stop the process temporarily.
Restart Discord normally.

This helps identify if a specific Discord process is causing the issue.
