The Windows 11 Gaming Overlay was built as a solution: a "layer" that sits on top of your game without closing it. It acts as a dashboard for your gaming life. It integrates widgets for performance monitoring (FPS, CPU, GPU usage), audio controls, Xbox chat, and even screen recording.
If you want to keep the recording features but hate the pop-ups, go into the Game Bar settings and disable notifications. This keeps the tool silent until you manually ask for it. ms gaming overlay popup windows 11
