Game Mode, located under Gaming in Windows 11/10 Settings, prioritizes system resources for games to reduce lag and frame-rate problems. Microsoft says it can make almost any game run more smoothly.
When enabled, it directs most CPU and GPU power toward the game and automatically stops unwanted or lower-priority background activity, such as random antivirus scans. You cannot choose which individual background processes stop or run while Game Mode is active.

- Enable Record game clips, screenshots, and broadcast using Game Bar.
- Launch a game and press Win + G to open Game bar.

When disabling Game Mode may help
The performance improvement depends on your hardware, and you may not notice a speed increase. In most cases, however, Game Mode does not cause problems that require turning it off.
Some users have reported system or application crashes and other unusual behavior with Game Mode enabled. Its reallocation of resources toward games can interfere with important background tasks and cause system issues. If you encounter these problems while gaming, disable Game Mode and try again.
