Type of Change

  • New feature
  • Bug fix

Description

Two changes to tweaks.json:

1. Added Game Mode toggle (WPFToggleGameMode)

New toggle under Customize Preferences to enable/disable Windows Game Mode via registry. Disabling Game Mode is useful for audio/video production users who find it interferes with recording/streaming performance.

Registry keys:

  • \HKCU\Software\Microsoft\GameBar\AllowAutoGameMode\
  • \HKCU\Software\Microsoft\GameBar\AutoGameModeEnabled\

2. Fixed MPO overlay for Windows 11 25H2

The existing \WPFToggleMultiplaneOverlay\ only used \Dwm\OverlayTestMode\ which is deprecated on 25H2. Added the new working path:

  • \HKLM...\GraphicsDrivers\DisableOverlays = 1\

Both registry entries are included so the toggle works on both old and new builds.
