MangoHud - Monitor FPS, CPU & GPU Usage in Linux Games

MangoHud: A powerful tool for real-time monitoring of Linux gaming performance

MangoHud is a powerful and lightweight tool designed for gamers, developers, and anyone who wants to monitor system performance in real time. It acts as an overlay for Vulkan and OpenGL applications, displaying important information such as FPS, CPU and GPU usage, temperature, etc. This article will explore the functions, working principles and usage of MangoHud, and provide step-by-step instructions for installing and configuring MangoHud on Linux systems.

What is MangoHud?

MangoHud is an open source project available on GitHub and aims to provide a simple and customizable way to monitor system performance when running Vulkan and OpenGL applications. The overlay is lightweight and does not take up a lot of system resources, so it does not interfere with the game or other tasks.

Key features of MangoHud:

• FPS Counter – Shows the current number of frames per second, helping to understand how smooth the game or application is running.
• CPU and GPU Usage – Displays the usage of processor and graphics cards.
• Temperature Monitoring – Track the CPU and GPU temperature to help you avoid overheating.
• Frame timing – provides information about the time it takes to render each frame.
• Custom – Allows you to change the position, size, and color of the overlay to suit your preferences.
• Supports multiple APIs – Works with Vulkan and OpenGL applications.

How to install MangoHud on Linux

MangoHud is found in the official repositories of many Linux distributions and can be installed using the default package manager.

 sudo apt install mangohud # Debian, Ubuntu and Mint

How to use MangoHud in Linux

Once installed, you can enable MangoHud for games and applications using simple commands.

Enable MangoHud for OpenGL applications

To run OpenGL games or applications using MangoHud, use:

 mangohud application_name

Enable MangoHud for Vulkan app

For Vulkan-based applications, just add mangohud before the command:

 mangohud vulkan_application

The overlay is displayed in the upper left corner by default, showing FPS, CPU/GPU usage, and other metrics.

MangoHud with Steam Games enabled

To use MangoHud in Steam games, go to the library , right-click on the game, select Properties , and add in the launch options :

 MANGOHUD=1 %command%

MangoHud will now be displayed when the game is started.

MangoHud with Proton Games enabled

For Windows games running through Proton, use the following command in Steam's startup options:

 MANGOHUD=1 PROTON_ENABLE_NVAPI=1 PROTON_NO_ESYNC=1 %command%

Configuring MangoHud in Linux

MangoHud allows users to customize overlays using profiles.

 <code>~/.config/MangoHud/MangoHud.conf</code>

You can modify the configuration file to change the display settings.

 <code>fps_limit=60 no_display=0 position=top-left background_alpha=0.4 font_size=24 cpu_temp=1 gpu_temp=1 ram=1</code>

You can also change settings while running the game using the following keyboard shortcuts:

• Shift F12 → Switch the switch of MangoHud.
• Shift F11 → Switch log mode.

Summarize

MangoHud is an excellent tool for Linux users to monitor system performance when running games or graphics applications. It provides real-time information about FPS, CPU/GPU usage, temperature and memory consumption to help users optimize the gaming experience.
