How to Boost PC Gaming with Microsoft Edge’s Efficiency Mode
Microsoft Edge’s Efficiency Mode boosts your PC gaming by reducing browser resource use.
This built-in browser feature automatically pauses background tabs and lowers CPU usage when it detects you’re gaming. This frees up more of your computer’s power specifically for your games.
Think of it as telling your browser to take a break so your games can run smoother, especially with demanding titles. Efficiency Mode helps prevent Edge from hogging your PC’s processing power.
Enable Microsoft Edge’s Efficiency Mode by going to Settings System and performance, then toggling on “Improve your PC gaming experience with efficiency mode.” This reduces browser resource usage, freeing up your PC for games.
Why use Microsoft Edge gaming efficiency?
Microsoft Edge’s gaming efficiency mode helps your PC run games better by stopping the browser from using too much power when you’re playing.
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
Let’s look at how Efficiency Mode compares to PC Gaming Boost. While both help your computer, they improve your gaming experience in slightly different ways.
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.

Boost your PC gaming experience by turning on Microsoft Edge's efficiency mode. This feature helps your games run smoother by managing the browser's resources. To enable Microsoft Edge gaming efficiency, open Edge, click the three dots in the top right, go to Settings, and then find the 'Optimize Performance' section. Toggle the switch for 'Improve your PC gaming experience with efficiency mode' to On.
Look for Optimize Performance. Toggle the switch for Improve your PC gaming experience with efficiency mode to On.

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.
How to check if it is working
If the feature isn't working, ensure your Windows Game Bar is enabled. Heads-up: the old GamerModeEnabled registry policy is no longer supported and you shouldn't use it. If you have issues, make sure your browser is updated to the latest version.
Technical Troubleshooting
If you're having trouble, check your PC's Task Manager. This will help confirm the browser is managing resources correctly for your games.
Summary
Does PC gaming boost impact my opened tabs?
Yes, it uses 'tab sleeping' technology to pause background activity. This frees up CPU (Central Processing Unit) and RAM (Random Access Memory - the computer's short-term memory) 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 heading to the same System and performance settings menu in Edge. Just toggle the switch to Off. You don't need to restart your browser; the change takes 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.
