GameOverlay vs Intel PresentMon

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.

Intel PresentMon is a free Windows application for monitoring and measuring gaming performance. It combines a customizable overlay, GPU telemetry, and capture functions for viewing data during or after a gaming session. The overlay can show real-time multi-line charts and histograms, plus raw numbers, percentiles, and rolling-window averages. Its GPU Busy metric presents CPU and GPU balance and resource use to help locate performance bottlenecks. PresentMon works with Intel Arc graphics cards and Intel Core processors, as well as hardware from other vendors. It supports applications using DirectX 12, DirectX 11, DirectX 9, OpenGL, and Vulkan on Windows 10 and Windows 11. Command-line functions support batch testing and automation. Intel describes it as open source, with third-party integration through the PresentMon SDK and API. Starting a trace requires Windows Performance Log Users membership or administrator privileges. GPU execution metrics may be less accurate with Hardware-Accelerated GPU Scheduling enabled.
