How to Boost PC Gaming with Microsoft Edge’s Efficiency Mode
If you want to improve your gaming performance, you can use built-in features in the Microsoft Edge browser. This guide explains how to use Microsoft Edge gaming efficiency to get the most out of your hardware.
Why use Microsoft Edge gaming efficiency?
Browsers often use a lot of your computer’s power even when you are not looking at them. When you start a game, your computer needs all the power it can get. This feature tells your browser to calm down while you play. This helps your games run smoother and faster by managing browser resource usage.
What happens when done?
Once enabled, your browser will automatically detect when you launch a game. It will then lower its own resource usage, leaving more room for your game to perform at its best. This is done through background tab throttling and resource management.
Efficiency Mode vs. PC Gaming Boost
It is important to know the difference. Efficiency Mode is a general setting that saves battery and memory by putting inactive tabs to sleep. PC Gaming Boost is a specific setting that works with the Windows Game Bar to detect when a game is running and prioritize your hardware for the game instead of the browser.
How to enable PC gaming efficiency
- Open the Microsoft Edge browser.
- Click the three dots (…) in the top right corner.
- Select Settings from the menu.

On the Settings page, select System and performance from the left menu or paste edge://settings/system into your address bar.
Look for Optimize Performance. Toggle the switch for Improve your PC gaming experience with efficiency mode to On.

How to check if it is working
You can verify this in the Task Manager. Press Ctrl + Shift + Esc while your game is running. Look for Microsoft Edge processes. You should see the browser usage drop significantly when the game is the active window.
Technical Troubleshooting
If the feature is not working, ensure your Windows Game Bar is enabled. Note that the old GamerModeEnabled registry policy is now obsolete and should not be used. If you have issues, ensure your browser is updated to the latest version.
Summary
Microsoft Edge offers powerful tools like gaming optimization settings to help your PC run better. By using efficiency mode and PC gaming boost, you reduce background resource throttling, allowing your games to use the full power of your hardware. Always check your Task Manager to ensure the settings are active during your play sessions.
Does PC gaming boost impact my opened tabs?
Yes, it uses tab sleeping technology to pause background activity. This frees up CPU and RAM for your game. Your tabs remain open, but they will refresh when you click on them again after you finish your gaming session.
How do I turn off PC gaming boost while playing?
You can turn it off by going to the same System and performance settings menu in Edge. Simply toggle the switch to Off. You do not need to restart your browser for this change to take effect immediately.
Is PC gaming boost compatible with all Windows versions?
This feature is primarily designed for Windows 10 and Windows 11. It relies on the Windows Game Bar integration. It is not available on macOS or older versions of Windows like Windows 7 or 8.
