Hardware Monitoring Overlay for Gamers

Real-time CPU, GPU temperature, and FPS directly on your screen — even inside fullscreen games.

Free Features

Everything you need to monitor your system while gaming — no license required.

Real-time Telemetry

CPU usage (%) and GPU temperature (°C) updated every second via a native C++ engine.

In-Game FPS Overlay

Uses Windows ETW (PresentMon) to display FPS when a known game is in the foreground.

Game Detection

Automatically detects 100+ popular games and shows the game name above metrics.

Always-on-Top

Overlay stays above fullscreen games and applications — never hidden.

Click-Through Mode

Overlay ignores mouse input so it never steals focus from your game.

Mini Mode

Compact 340×45 bar showing just FPS — toggle with double-click or tray menu.

Auto-Hide When Idle

Overlay fades out when you're not in a game — no clutter on the desktop.
