How to Fix the Epic Games Launcher’s High CPU Usage on Windows

If your Epic Games Launcher is causing high CPU usage on your Windows PC, it can slow down your system, cause overheating, and impact gaming performance. Fixing this issue ensures smoother operation, reduces system strain, and improves overall responsiveness. Before starting, make sure your Windows OS is up to date, and you have administrator rights on your PC. Having a stable internet connection is also helpful since some fixes require downloading updates or tools.

What You’ll Need

  • A Windows PC with administrative privileges
  • Internet connection
  • Basic knowledge of Windows settings
  • Optional: a system cleaning or optimization tool (like CCleaner)

Step-by-Step

  1. Close the Epic Games Launcher – Ensure the launcher is completely closed. Right-click the Epic Games icon in the system tray and select “Exit” or use Task Manager (press Ctrl + Shift + Esc) to end the Epic Games process.
  2. Restart Your PC – A simple restart can resolve temporary glitches causing high CPU usage.
  3. Run the Epic Games Launcher as Administrator – Right-click the launcher shortcut and select “Run as administrator.” This grants the app necessary permissions and can reduce resource conflicts.
  4. Update the Epic Games Launcher – Open the launcher, go to the settings menu (click the gear icon), and check for updates. If an update is available, install it. Updated versions often fix bugs that cause high CPU use.
  5. Clear the Cache – Corrupted cache files can cause performance issues. Close the launcher, then navigate to the cache folder:

    – Press Win + R, type %localappdata%, and hit Enter.
    – Locate the Epic Games folder, then find and delete the “WebCache” folder.
    – Restart the launcher and check CPU usage.

  6. Disable Background Processes – Open Task Manager (Ctrl + Shift + Esc), go to the “Processes” tab, and identify any resource-heavy processes unrelated to Epic Games. End unnecessary processes to free CPU resources.
  7. Adjust Epic Launcher Settings – Within the launcher, go to Settings > Preferences, and disable options like “Enable Background Updates” or “Allow Automatic Updates”. These can run in the background, consuming CPU.
  8. Check for Windows Updates – Ensure your Windows OS is fully updated. Go to Settings > Update & Security > Windows Update, and install any pending updates.
  9. Scan for Malware – Run a full system scan with your antivirus or Windows Defender. Malicious software can cause high CPU usage and interfere with legitimate applications.
  10. Reinstall the Epic Games Launcher – If problems persist, uninstall the launcher via Control Panel > Programs, then download the latest version from the official website and reinstall it. This can resolve corrupted files causing high CPU usage.

Common Mistakes

  • Ignoring updates: Failing to update the launcher can leave bugs unresolved.
  • Closing background processes improperly: Ending system-critical processes can destabilize Windows.
  • Disabling essential services: Turning off Windows services needed for system stability can cause more issues.
  • Skipping cache clearing: Corrupted cache files are a common cause of performance problems.
  • Overlooking malware scans: Malware can mimic or cause high CPU usage, so neglecting security scans is a mistake.

Tips

  • Schedule regular system maintenance, including updates and disk cleanup.
  • Use the Task Manager to monitor CPU usage patterns and identify culprits.
  • Consider optimizing startup programs to reduce background load.
  • Adjust in-game or launcher settings to lower resource demands if you experience lag.
  • Keep your graphics drivers and Windows OS up to date for optimal performance.

Troubleshooting

If your CPU usage remains high after following the steps above, try these additional solutions:

  • Perform a Clean Boot – This starts Windows with minimal drivers and startup programs, helping identify if third-party software causes the issue. To do this, type “msconfig” in the Start menu, go to the “Services” tab, check “Hide all Microsoft services,” then disable the remaining services. Restart your PC and test the launcher.
  • Check for System Conflicts – Use Windows Event Viewer to identify errors related to Epic Games or system conflicts. Search for recent error logs and address any identified issues.
  • Reset the Epic Games Launcher Settings – Delete or rename the launcher configuration files located in %localappdata% and %appdata%. Restart the launcher to regenerate default settings.
  • Upgrade Hardware – If your PC’s CPU is outdated or underpowered, consider upgrading hardware components for better performance.

Persistent high CPU usage issues might indicate deeper system problems or hardware limitations. If none of these solutions work, reaching out to Epic Games support or consulting a professional technician is advisable.

Frequently Asked Questions

1. Why is the Epic Games Launcher using so much CPU?

This can happen due to outdated software, corrupted cache files, background updates, or conflicts with other programs. Sometimes, malware can also cause high CPU load.

2. How do I know if my CPU usage is abnormal?

If the launcher consistently consumes over 50% CPU when idle or during normal operation, it’s abnormal. Use Task Manager to monitor CPU percentage and identify spikes.

3. Will reinstalling the Epic Games Launcher delete my games?

No, uninstalling the launcher only removes the app itself. Your installed games are stored in separate folders, but always back up game files before reinstalling for safety.

4. Can hardware upgrades fix high CPU usage issues?

Yes, if your CPU is outdated or underpowered, upgrading can improve overall performance, reducing high usage caused by resource limitations.

5. How often should I clear cache files for optimal performance?

It’s recommended to clear cache files every few months or when you notice performance drops or launcher errors.

6. Is it safe to disable background updates?

Disabling background updates can prevent high CPU usage when idle, but ensure you manually update the launcher regularly to stay secure and bug-free.
