MangoHud

A modification of the Mesa Vulkan overlay. Including GUI improvements, temperature reporting, and logging capabilities.

Example:

Installation

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

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

Then simply run the following commands:

./build.sh build
./build.sh package
sudo ./build.sh install


If you are running an Ubuntu-like distribution, Fedora, or Arch, 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!

Packaging status

Fedora: sudo dnf install mangohud

Arch: Install mangohud and lib32-mangohud with your favourite AUR helper. mangohud-git is also available on the AUR.

Normal usage

To enable the MangoHud Vulkan overlay layer, run :

MANGOHUD=1 /path/to/my_vulkan_app

Or alternatively, add MANGOHUD=1 to your shell profile.

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
  4. $HOME/.local/share/MangoHud/MangoHud.conf

The default config file is installed to $HOME/.config/MangoHud/MangoHud.conf and will not be overwritten by the script.


MANGOHUD_CONFIG environment variable

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.

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
ram
vram
Displays system RAM/VRAM usage
full Enables all of the above config options
crosshair Adds a crosshair overlay at the centre of the screen
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
no_display Hide the hud by default
toggle_hud=
toggle_logging=
Modifiable toggle hotkeys. Default are F12 and F2, respectively.
reload_cfg= Change keybind for reloading the config
time
time_format=%T
Displays local time. See std::put_time for formatting help.
gpu_color
gpu_color
vram_color
ram_color
io_color
engine_color
frametime_color
background_color
text_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

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

Vulkan Vsync

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

Keybindings

  • F2 : Toggle Logging
  • F4 : Reload Config
  • F12: Toggle Hud

MangoHud FPS logging

When you toggle logging (using the keybind F2), a file is created with your chosen name (using MANGOHUD_OUTPUT) 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.
