How to Boost PC Gaming with Microsoft Edge’s Efficiency Mode
You can boost your PC gaming performance by enabling Microsoft Edge’s Efficiency Mode.
Efficiency Mode is a built-in browser feature designed to reduce Microsoft Edge’s resource consumption, specifically by limiting background tab activity and lowering CPU usage.
This means more of your PC’s processing power is available for your games, potentially leading to higher frame rates and smoother gameplay. This feature is particularly helpful when running demanding titles like Cyberpunk 2077 or Elden Ring, where every bit of performance counts.
When you activate Efficiency Mode, Edge automatically pauses inactive tabs and reduces their power draw, ensuring it doesn’t hog resources while you’re immersed in your favorite game.
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
Microsoft Edge’s Efficiency Mode and PC Gaming Boost both help your computer, but they work a bit differently to improve your gaming experience.
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.

Turning on Microsoft Edge’s gaming efficiency mode is simple and helps your games run smoother by managing browser resources.
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. Just a 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 with Microsoft Edge’s gaming efficiency settings, checking your PC’s Task Manager can 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) 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 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.
