How to Completely Disable ‘Game Mode’ (Background Resource Reallocation) in Windows 11

Windows 11 features a built-in optimization engine called “Game Mode.” When the operating system detects that you have launched a full-screen video game, this daemon activates in the background. Its purpose is to violently reallocate system resources—suspending background tasks, blocking Windows Updates, pausing driver installations, and prioritizing CPU/GPU cycles exclusively for the game executable.

While this sounds excellent for gamers on low-end hardware, it can cause catastrophic issues for streamers, content creators, and power users. If you are playing a game while simultaneously using OBS Studio to stream, capturing video via Nvidia Shadowplay, or rendering a 3D model in Blender in the background, Game Mode will actively throttle those essential background applications, resulting in dropped frames on your stream or corrupted video recordings. If your PC has plenty of CPU cores and RAM to handle multitasking, you must completely disable Game Mode to prevent the OS from starving your background apps.

Disabling Game Mode via Windows Settings

Microsoft placed the master toggle switch for this feature directly in the modern Settings app.

1. Click the Start button and select the Settings gear icon (or press Windows Key + i).
2. In the left-hand navigation sidebar, click on Gaming.
3. In the main panel, click on Game Mode.
4. You will see a single master toggle switch labelled Game Mode.
5. Click the switch to turn it Off.

Disabling Game Mode via the Registry (For System Admins)

If you are managing a fleet of workstations and want to ensure Game Mode is permanently killed at the system level, you can enforce this via the Windows Registry.

1. Press the Windows Key + R to open the Run dialogue box.
2. Type regedit and press Enter (Click Yes on the UAC prompt).
3. Navigate to this exact path:
   HKEY_CURRENT_USER\Software\Microsoft\GameBar
4. Look for a DWORD value named AllowAutoGameMode. If it does not exist, right-click in the empty space, select New > DWORD (32-bit) Value, and name it exactly AllowAutoGameMode.
5. Double-click on it and ensure the “Value data” is set to 0.
6. Click OK and restart the computer.

From this point forward, Windows 11 will treat your video games exactly like any other application. It will distribute CPU and GPU resources fairly across all your active programs, ensuring that OBS Studio and other critical background tasks never drop frames while you play.
