Problem overview

While Windows Game Mode is designed to improve performance by prioritizing resources for games, it can sometimes cause severe stuttering or FPS drops, especially if you have other intensive background apps running.

Common causes

  • Game Mode fighting for resources against streaming software like OBS
  • Conflicts with Xbox Game Bar or other active overlays
  • Per-game fullscreen optimization issues overriding Game Mode behavior
  • Specific driver bugs that conflict with Windows scheduling

Solution 1: Disable Windows Game Mode

  1. Press Win + I to open Windows Settings.
  2. Select Gaming from the left-hand menu.
  3. Click on Game Mode.
  4. Toggle the switch to Off.
  5. Launch your game to see if the stuttering is resolved.
Expert Tip

If disabling Game Mode fixes your stuttering while recording or streaming, keep it off permanently, as OBS requires high background priority.

Solution 2: Disable Xbox Game Bar

  1. Go back to Settings > Gaming.
  2. Click on Xbox Game Bar.
  3. Toggle the switch for Open Xbox Game Bar using this button on a controller to Off.
  4. Open Installed apps in Settings, search for Xbox Game Bar, click the three dots, select Advanced options, and change the background permissions to Never.

Solution 3: Disable fullscreen optimizations per-game

  1. Locate the main .exe file of the game causing issues (e.g., in your Steam steamapps folder).
  2. Right-click the executable and select Properties.
  3. Navigate to the Compatibility tab.
  4. Check the box for Disable fullscreen optimizations.
  5. Click Apply and then OK.
Caution

Disabling fullscreen optimizations can prevent you from easily alt-tabbing out of some games, so only use this setting if you are actively troubleshooting stuttering.

Confirm the result

  1. Repeat the exact action that originally triggered the problem.
  2. Confirm the original error or symptom is gone and no new warning has appeared.
  3. If the guide changed a driver, service, package, or system setting, restart once and test again.
  4. If the result is worse or unexpected, stop. Reverse only the last change using its documented restore option; if none is documented, use your backup or qualified support.

Questions about this fix

What does Windows Game Mode actually do?

It de-prioritizes background tasks and Windows updates to allocate more CPU and GPU resources to your active game.

Is it better to leave it on or off?

For most users, leave it on. If you stream using OBS or experience weird stutters, try turning it off.
