If you face issues starting the game, learn what to do when Overwatch 2 isn’t launching.

Why does Overwatch 2 take up so much CPU?

Overwatch 2 is a CPU-demanding game, so it doesn’t surprise it takes a lot of processing power. However, it can also occur due to temporary issues on your PC, unnecessary background apps, faulty overclock settings, inappropriate in-game settings, an outdated GPU driver, or unnecessary startup services.

How to fix high CPU usage in Overwatch 2?

Let’s start with some easy checks and fixes:

  • Check the system requirements: A bottleneck might appear if your GPU meets the Overwatch 2 requirements, but the CPU doesn’t.
  • Restart your PC: Some gamers claim they fix the issue by restarting their PC, and from then on, the problems with high CPU usage disappear.
  • Close background apps: Before launching Overwatch 2 or Battle.net, close all visible apps from the taskbar. Additionally, use the Task Manager to disable background processes.
  • Disable overclock settings: If you overclocked your CPU to gain more computing power, disable these settings and check if high usage occurs.

Apply the step-by-step solutions from the list below.

  1. Tweak in-game settings
  2. Update the GPU driver

3. Disable startup services

Each time you boot your operating system, many startup services start with it. These background tasks are invisible in the taskbar but will consume your PC’s resources, including the CPU, which can lead to high CPU usage when trying to play Overwatch 2.

  1. Use the Windows shortcut, type msconfig, and hit Enter.
  2. Navigate to the Services tab.
  3. Check Hide all Microsoft services and then hit the Disable All button.
  4. Click OK and restart your PC.

Extra steps

Here are some additional fixes if Overwatch 2 CPU usage stays high even after doing everything else we proposed:

  • 💻 Limit the FPS: Find the option for FPS limiting in your graphics card settings. Some gamers report that this fixed the issue, as the game didn’t try to deliver hundreds of FPS.
  • 🔋 Change the Power Plan: If you are playing Overwatch 2 on a laptop, click on the battery icon in the taskbar and set the Power Plan to the Best Performance.
  • 🥶 Keep it cool: Ensure proper ventilation and change the thermal paste on your CPU to avoid overheating, which can lead to high CPU usage.
  • ⏳ Be patient: Some gamers claim they can only load the game and wait a few minutes before playing it. This way initial load is handled efficiently, and CPU usage doesn’t get high.
