GameOverlay vs PlayClaw

GameOverlay is a free Windows utility that places performance statistics over games. It can display FPS, 1% and 0.1% low FPS, ping, packet loss, and CPU and GPU usage and temperatures. FPS capture uses bundled Intel PresentMon, and low-FPS figures are calculated from frame times. In Auto mode, network monitoring identifies a game server from traffic and pings the address exchanging the most packets with the game. Each metric has its own visibility control and color picker; users can also adjust position, font, size, opacity, and background box. The overlay stays on top, allows clicks to pass through, and saves changes to a configuration file. Downloads include a standalone executable and a folder ZIP, and the project documents running from source with Python 3.10 or later on Windows. Administrator access is required for CPU temperature readings, FPS capture, and ping detection; declining it can leave those readings unavailable. The overlay cannot draw over exclusive-fullscreen games, so the maker recommends borderless or windowed fullscreen mode. The project is MIT licensed, and the bundled sensor library is under MPL 2.0.
