Windows 11 aggressive energy-saving features can sometimes throttle Desktop Window Manager (DWM) composition on secondary displays or when playing full-screen games, resulting in a perceived stutter on secondary screens.
DWMfix is a background utility that forces the Windows DWM to maintain high-performance composition by constantly rendering an imperceptible transparent widget. This prevents the OS from putting the rendering layer into a low-power, low-refresh state, keeping your second monitor stutter-free.
- Run
DWMfix.exe. - A control panel will appear where you can manage the tool, toggle boost mode, or hide it to the system tray.
- Keep it running in the tray while gaming or using your secondary monitor.
If this tool helped you fix your dual monitor stuttering, consider supporting the development!
