Straight answers, no fluff

Visor is a real-time hardware monitor for Windows 10 and 11. It shows CPU, GPU, RAM, motherboard, storage, network, display, battery and in-game FPS, explains them in plain language, and uses Smart Check to find settings that cost you frames. It's made by Tetono in Thailand, free forever, with an optional one-time Pro upgrade for US$2.99.

Windows 10 and Windows 11, 64-bit. It needs .NET Framework 4.8, which is already built into both. There is no Mac, Linux or mobile version.

Visor reads what your hardware's sensors report, through LibreHardwareMonitor, a widely used open-source library, and never adjusts the numbers. Accuracy therefore depends on each part's sensors. Readings can differ slightly from other tools because they sample at different moments or pick a different sensor, such as package versus per-core temperature.

Low-level sensors such as per-core CPU temperatures, voltages and motherboard fans need PawnIO, and some hardware, laptops especially, doesn't report certain values at all. Visor tells you a value can't be read rather than guessing.

Visor only reads values and draws them; it runs no heavy background work. Our target is under 2% CPU and under 150 MB of RAM while updating every second. The overlay draws in its own window and doesn't run inside the game.

English and Thai. The installer picks the language that matches your Windows.

Visor is designed not to touch your game: no DLL injection, no graphics hooks, no reading game memory. The overlay is a transparent window on top, FPS comes from PresentMon reading Windows events, and sensors are read through PawnIO rather than the old WinRing0 driver some anti-cheat systems block.

PawnIO is a signed, open-source driver for reading low-level sensors. It replaces the old WinRing0 driver that Windows Defender flags as risky. Visor has no driver of its own and doesn't bundle PawnIO: the app asks first and opens the official installer from pawnio.eu if you agree. It's optional, and you can remove it any time from Settings › Apps.

No, by design. Visor is read-only: no fan control, no overclocking, no voltage changes and no BIOS changes, because a monitoring tool should never be the thing that damages your PC.

Only three Windows settings that can always be switched back: display refresh rate, power plan and Windows Game Mode. Each one asks for confirmation first and comes with an undo. It's a Pro feature.

Windows SmartScreen warns about new programs that haven't been downloaded by many people yet or aren't digitally signed. It doesn't mean the file is harmful. Click More info, then Run anyway, and only download from https://visor.tetono.com.

Visor has no telemetry and no ads. Your hardware details, sensor readings and history stay on your PC. The app only goes online to start a trial and to activate and check a Pro license, sending the key, a one-way hashed machine ID and the app version. Read the privacy policy.

No. It shows your parts, display, storage and health score, with no PC name or user name. It's created on your PC and isn't uploaded anywhere.
