MangoHud

A Vulkan and OpenGL overlay for monitoring FPS, temperatures, CPU/GPU load and more.

Example:

Installation

Build

If you wish to compile MangoHud to keep up to date with any changes - first clone this repository and cd into it:

git clone --recurse-submodules https://github.com/flightlessmango/MangoHud.git
cd MangoHud

To build it, execute:

./build.sh build
./build.sh package

NOTE: If you are running an Ubuntu-based, Arch-based, Fedora-based, or openSUSE-based distro, the build script will automatically detect and prompt you to install missing build dependencies. If you run into any issues with this please report them!

Once done, proceed to the installation.

Install

Source

If you have compiled MangoHud from source, to install it, execute:

./build.sh install

Pre-packaged binaries

GitHub releases

If you do not wish to compile anything, simply download the file under Releases, extract it, and run ./mangohud-setup.sh install from within the extracted folder.

Arch-based distributions

If you are using an Arch-based distribution, install mangohud and lib32-mangohud with your favourite AUR helper. mangohud-git and lib32-mangohud-git are also available on the AUR if you want the up-to-date version of MangoHud.

Fedora

If you are using Fedora, to install the MangoHud package, execute:

sudo dnf install mangohud

Flatpak

If you are using Flatpaks, you will have to add the Flathub repository for your specific distribution, and then, to install it, execute:

For Steam flatpak

flatpak install com.valvesoftware.Steam.Utility.MangoHud

To enable MangoHud for all Steam games:

flatpak override --user --env=MANGOHUD=1 com.valvesoftware.Steam

Normal usage

To enable the MangoHud overlay layer for 64bit Vulkan and OpenGL, run :

mangohud /path/to/app

Or

mangohud.x86 /path/to/app for 32bit OpenGL

For Lutris games, go to the System options in Lutris (make sure that advanced options are enabled) and add this to the Command prefix setting:

mangohud

For Steam games, you can add this as a launch option:

mangohud %command%

Or alternatively, add MANGOHUD=1 to your shell profile (Vulkan only).

OpenGL

OpenGL games may also need dlsym hooking. Add MANGOHUD_DLSYM=1 to your command like MANGOHUD_DLSYM=1 mangohud %command% for Steam.

Some Linux native OpenGL games overrides LD_PRELOAD and stops MangoHud from working. You can sometimes fix this by editing LD_PRELOAD in the start script LD_PRELOAD=/path/to/mangohud/lib/

Hud configuration

MangoHud comes with a config file which can be used to set configuration options globally or per application. The priorities of different config files are:

1. /path/to/application/dir/MangoHud.conf
2. $HOME/.config/MangoHud/{application_name}.conf
3. $HOME/.config/MangoHud/MangoHud.conf

You can find an example config in /usr/share/doc/mangohud

GOverlay is a GUI application that can be used to manage the config

---

MANGOHUD_CONFIG and MANGOHUD_CONFIGFILE environment variables

You can also customize the hud by using the MANGOHUD_CONFIG environment variable while separating different options with a comma. This takes priority over any config file.

You can also specify configuration file with MANGOHUD_CONFIGFILE=/path/to/config for applications whose names are hard to guess (java, python etc).

A partial list of parameters are below. See the config file for a complete list.

Variable	Description
cpu_temp gpu_temp	Displays current CPU/GPU temperature
core_load	Displays load & frequency per core
gpu_core_clock gpu_mem_clock	Displays GPU core/memory frequency
ram vram	Displays system RAM/VRAM usage
full	Enables all of the above config options
font_size=	Customizeable font size (default=24)
width= height=	Customizeable hud dimensions (in pixels)
position=	Location of the hud: top-left (default), top-right, bottom-left, bottom-right, top-center
offset_x offset_y	Hud position offsets
no_display	Hide the hud by default
toggle_hud= toggle_logging=	Modifiable toggle hotkeys. Default are Shift_R+F12 and Shift_L+F2, respectively.
reload_cfg=	Change keybind for reloading the config. Default = Shift_L+F4
time time_format=%T	Displays local time. See std::put_time for formatting help. NOTE: Sometimes apps (or AMDVLK) may set TZ environment variable to GMT+0
gpu_color gpu_color vram_color ram_color io_color engine_color frametime_color background_color text_color media_player_color	Change default colors: gpu_color=RRGGBB
alpha	Set the opacity of all text and frametime graph 0.0-1.0
background_alpha	Set the opacity of the background 0.0-1.0
read_cfg	Add to MANGOHUD_CONFIG as first parameter to also load config file. Otherwise only MANGOHUD_CONFIG parameters are used.
output_file	Define name and location of the output file (Required for logging)
font_file	Change default font (set location to .TTF/.OTF file )
log_duration	Set amount of time the logging will run for (in seconds)
vsync gl_vsync	Set vsync for OpenGL or Vulkan
media_player	Show media player metadata
media_player_name	Set main media player DBus service name without the org.mpris.MediaPlayer2 part, like spotify, vlc, audacious or cantata. Defaults to spotify.
media_player_order	Media player metadata field order. Defaults to title,artist,album.
font_scale_media_player	Change size of media player text relative to font_size
io_read io_write	Show non-cached IO read/write, in MiB/s
pci_dev	Select GPU device in multi-gpu setups
version	Shows current mangohud version
fps_limit	Limit the apps framerate
arch	Show if the application is 32 or 64 bit
histogram	Change fps graph to histogram
cpu_text gpu_text	Override CPU and GPU text
log_interval	Change the default log interval, 100 is default
vulkan_driver	Displays used vulkan driver, radv/amdgpu-pro/amdvlk
gpu_name	Displays GPU name from pci.ids
gpu_power	Display GPU draw in watts

Example: MANGOHUD_CONFIG=cpu_temp,gpu_temp,position=top-right,height=500,font_size=32

Note: Width and Height are set automatically based on the font_size, but can be overridden.

Vsync

OpenGL Vsync

• -1 = Adaptive sync
• 0 = Off
• 1 = On
• n = Sync to refresh rate / n.

Vulkan Vsync

• 0 = Adaptive VSync (FIFO_RELAXED_KHR)
• 1 = Off (IMMEDIATE_KHR)
• 2 = Mailbox (VSync with uncapped FPS) (MAILBOX_KHR)
• 3 = On (FIFO_KHR)

All vulkan vsync options might not be supported on your device, you can check what your device supports here vulkan.gpuinfo.org

Keybindings

• Shift_L+F2 : Toggle Logging
• Shift_L+F4 : Reload Config
• Shift_R+F12: Toggle Hud

MangoHud FPS logging

When you toggle logging (using the keybind Shift_L+F2), a file is created with your chosen name (using output_file) plus a date & timestamp.

This file can be uploaded to Flightlessmango.com to create graphs automatically. you can share the created page with others, just link it.

Multiple log files

It's possible to upload multiple files when using Flightlessmango.com. You can rename them to your preferred names and upload them in a batch. These filenames will be used as the legend in the graph.
