How to Enable Windows Game Mode for Better Gaming Performance

What Causes This?

Windows Game Mode is designed to prioritize your game by reducing background activity and giving the game more consistent access to CPU and GPU resources. If Game Mode is turned off, Windows may allow updates, background apps, notifications, and other processes to compete with your game.

Performance issues can also happen when Game Mode is enabled but other Windows gaming features, startup apps, or overlays are still using system resources. On lower-end PCs, even small background tasks can cause stuttering, input lag, or frame drops while gaming.

Common Symptoms

• Games stutter when background apps are open
• Frame rates drop during gameplay for no clear reason
• Input feels delayed or less responsive
• Windows notifications or updates interrupt gaming sessions
• The PC feels busy in the background even when only a game is open

How to Fix It Manually

1. Turn on Game Mode in Windows Settings

   • Press Windows + I to open Settings.
   • Click Gaming.
   • Select Game Mode from the left sidebar.
   • Turn Game Mode On.

2. Make sure your game is running in its normal full-screen or borderless mode

   • Open your game.
   • Go to the game’s Graphics or Display settings.
   • Set it to Fullscreen or Borderless Fullscreen if available.
   • Some games respond better to Game Mode when they are not running in a small window.

3. Close unnecessary background apps before launching a game

   • Press Ctrl + Shift + Esc to open Task Manager.
   • Under the Processes tab, look for apps you do not need, such as browsers, launchers, chat apps, or RGB tools.
   • Right-click the app and choose End task.
   • Be careful not to close Windows system processes or anything you do not recognize.

4. Disable unneeded startup apps

   • In Task Manager, click the Startup tab. On Windows 11, you may need to click Startup apps in the left panel.
   • Review apps marked Enabled.
   • Right-click any non-essential app and choose Disable.
   • Restart your PC after making changes.

5. Turn off Xbox Game Bar if you do not use it

   • Press Windows + I to open Settings.
   • Go to Gaming > Xbox Game Bar.
   • Turn it Off if you do not use its recording or overlay features.
   • This can reduce background overhead on some systems.

6. Check for Windows and graphics driver updates

   • Open Settings > Windows Update and click Check for updates.
   • Then update your graphics driver through NVIDIA App, AMD Software: Adrenalin Edition, or Intel Driver & Support Assistant.
   • Outdated drivers can limit the benefit of Game Mode and cause poor game performance.

7. Restart the PC and test the game again

   • Save your work and restart Windows.
   • Launch the game and compare performance.
   • If the game still stutters, another background process or system setting may be interfering.
