The record

Purpose: GameOverlay is a lightweight, customizable in-game performance overlay for Windows.
Performance metrics: It displays FPS, 1% and 0.1% low FPS, ping, packet loss, CPU usage and temperature, and GPU usage and temperature.
Customization: Each metric has its own visibility toggle and color picker, and users can change the overlay position, font, size, opacity, and background box.
FPS integration: FPS capture uses bundled Intel PresentMon and derives low-FPS figures from frame times.
Network monitoring: In Auto mode, it detects the game server from network traffic and pings the address exchanging the most packets with the game.
Supported games: The README says FPS, ping, and packet loss show as unavailable when no game is active, and notes that Counter-Strike 2 can report an exact ping while some games require an approximate reading.
Display limitation: The overlay cannot draw over exclusive-fullscreen games, so the README recommends Borderless or Windowed Fullscreen mode.
Downloads: The project offers a standalone GameOverlay.exe and a GameOverlay-folder.zip, and also documents running from source with Python 3.10 or later on Windows.
Security: The README says the single-file executable is unsigned and may trigger antivirus heuristics; it suggests the folder ZIP or running from source as alternatives.
Permissions: The app requests administrator access for CPU temperature sensors, FPS capture, and ping detection; declining can leave those metrics unavailable.
License: The project is licensed under MIT and bundles LibreHardwareMonitorLib under MPL 2.0 and Intel PresentMon under MIT.
Maker: The repository identifies kynemyers as its owner and the release author.
Appearance controls: Each metric has its own visibility toggle and color picker, and users can change position, font, font size, opacity, and background box.
Overlay behavior: The overlay is always on top and click through, and changes apply instantly and are saved to a configuration file.
