GameOverlay vs Overwolf

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.

Overwolf is a platform for creating and using apps alongside games. Apps can show live game statistics, record video, or manage mods across more than 1,500 supported games. Users can access it without signing in or creating an account, and the Overwolf Appstore offers apps for PC games. Creators can use its SDK to build game overlays and desktop apps with JavaScript and HTML; the developer suite includes real-time alerts, a Game Event API, monetization tools, performance optimization, analytics, and support. CurseForge is its mod hub for games including Minecraft, World of Warcraft, and The Sims 4. Published apps are manually checked for quality, malware, performance, and compliance with game-developer terms. Overwolf says it anonymizes data used to improve the experience and lets users opt out. The Windows version requires Windows 10 or 11 64-bit, 350 MB of storage,.NET Framework 4.8, and at least 8 GB of RAM. Overwolf costs nothing; some apps may require subscriptions.
