Hub: Gaming Errors Hub

Quick Answer
Epic Games Launcher high CPU usage is usually caused by background downloads, a Chromium-based interface, corrupted cache files, or outdated drivers. The fastest fixes include clearing the launcher cache, updating your graphics driver, and disabling background downloads. For persistent issues, changing your power plan to “Best Performance” or repairing the launcher often resolves the problem immediately.

Why Epic Games Launcher High CPU Usage Happens

When Epic Games Launcher high CPU usage becomes a recurring issue, it can significantly impact your gaming experience. Even when the launcher is minimized to the system tray, it may consume excessive CPU resources, causing slower game performance, louder fans, higher temperatures, and reduced battery life on laptops[reference:0]. Understanding why Epic Games Launcher high CPU usage happens is the first step toward fixing it.

The most common cause is the launcher’s Chromium-based interface. The store, videos, animations, and interactive elements are rendered as if in a browser, which by design consumes CPU and RAM[reference:1]. This is a fundamental architectural choice that makes the launcher more resource-intensive than lighter alternatives. Epic Games has acknowledged this issue and is rebuilding the launcher from scratch, promising a five-times faster startup and improved system performance in 2026[reference:2].

Another frequent culprit is background downloads and patches. The launcher constantly looks for updates for itself and for every game in your library. If you have a large game library, this traffic is constant and can spike CPU usage[reference:3]. Similarly, preloading data and metadata to speed up access to the store and game information involves CPU cycles and disk activity[reference:4].

Other causes include corrupted cache files, which can cause various issues including high CPU consumption[reference:5], outdated graphics drivers[reference:6], compatibility issues with other installed applications[reference:7], and in-app bugs or glitches[reference:8].

⚠️ Warning: Epic Games has confirmed that the current launcher has performance issues and is working on a complete rebuild expected in mid-2026[reference:9]. Until then, the fixes below will help mitigate the problem.

1. Restart Your System

The simplest and most effective first step when you notice Epic Games Launcher high CPU usage is to restart your system. The problem can result from a temporary system glitch, and a restart clears temporary memory and resets system processes[reference:10].

  1. Close the Epic Games Launcher completely.
  2. Restart your Windows PC.
  3. After the restart, open the launcher and check if CPU usage has returned to normal.

✅ Expected Result: The launcher should consume fewer CPU resources. If Epic Games Launcher high CPU usage persists, proceed to the next method.

2. Download the Latest Windows Update

Outdated Windows versions can cause Epic Games Launcher high CPU usage because the launcher relies on the latest system optimizations. Installing the latest Windows updates can resolve compatibility issues[reference:11].

  1. Open Settings using Win + I.
  2. Choose Windows Update from the left pane.
  3. Click on Check for Updates.
  4. Windows will check for and download any pending updates[reference:12].
  5. Restart your system after installation.

💡 Quick Tip: If you’re on Windows 11, you can also try the Optimizations for windowed games in Windows 11 as recommended by Epic Games[reference:13].

3. Change the Power Plan to Best Performance

Windows power plans can limit system performance to save battery. If your power plan is set to “Power efficiency” or “Balanced,” you may experience Epic Games Launcher high CPU usage as the system struggles to keep up[reference:14].

  1. Open Settings.
  2. Under the System tab, choose Power & battery.
  3. Click on the drop-down icon next to Power mode.
  4. Select the “Best performance” option[reference:15].
  5. Relaunch the Epic Games Launcher and check CPU usage.

🔁 Alternative Solution: On desktop PCs, you can also access power options via Control Panel > Power Options and select “High Performance.”

4. Update the Graphics Driver

Outdated graphics drivers are a common cause of Epic Games Launcher high CPU usage. The launcher requires the latest graphics driver to run efficiently[reference:16].

  1. Open Device Manager by pressing Win + X and selecting Device Manager from the context menu[reference:17].
  2. Double-click on Display adapters to expand the menu[reference:18].
