Windows 11 includes a "Game Mode" enabled by default that automatically optimizes your system for gaming when it detects a game in progress. It usually works well, but if it causes performance problems, you can switch easily disable it. Here's how.
What Is Game Mode?
Game Mode is a special mode that prioritizes game processes as they run, ideally allowing them to run faster with fewer performance problems. Game Mode also temporarily prevents Windows Update from installing drivers (which might disrupt your gameplay) or asking to restart your PC. The feature originated with the Windows 10 Creators Update in 2017.
Very rarely, Game Mode can cause performance problems when in use. If that's the case, you can switch it off easily in Settings. Otherwise, you can safely leave Game Mode enabled, because it only activates when Windows 11 detects that you're playing a game.
How to Disable Game Mode in Windows 11
First, open Windows Settings by pressing Windows+i. Or you can right-click the Start button in your taskbar and select "Settings" in the menu that appears.
In Settings, click "Gaming" in the sidebar, then select "Game Mode."
In Game Mode settings, click the switch beside "Game Mode" to turn it "Off."
After that, close Settings. If you'd ever like to re-enable Game Mode, just revisit Settings > Game Mode and switch "Game Mode" to "On." Happy gaming!
