Windows Game Mode: on or off?

You still find advice online to turn Game Mode off, even though it's on by default in Windows 10 and 11. What it actually does, where the complaints came from and what to choose.

What Game Mode does

While a game is in the foreground, Windows gives it priority, doesn't start installing updates and doesn't show notifications that could knock you out of fullscreen. It doesn't “overclock” your PC or change graphics settings. So average FPS usually stays the same, while occasional drops caused by background tasks may happen less often.

Where the “turn it off” advice comes from

The first versions of Game Mode in early Windows 10 builds really did cause stutters in some games, and “turn off Game Mode” advice spread across forums and videos. Since then the mode has been reworked and turned on by default. Today problems are rare — mostly in very old games and unusual configurations.

How to check and switch it

Settings → Gaming → Game Mode. The switch is stored as AutoGameModeEnabled under HKCU\Software\Microsoft\GameBar. No restart needed. Don't confuse it with Game Bar background recording — those are different settings, and turning the second one off does make sense if you don't use it.

What to choose

• Keep it on — that's the right choice for almost everyone.
• If a particular game starts stuttering, turn the mode off, test the same scene and compare. If it helped, keep it off; if not, turn it back on and look for the cause elsewhere.

If you want a noticeable gain, Game Mode isn't the main lever. The power plan, an up-to-date graphics driver and a tidy startup list do more; see how to raise FPS on Windows.
