Installation

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 command:

./build.sh install

This will build and copy libMangoHud.so & libMangoHud32.so to $HOME/.local/share/MangoHud, as well as copying the required Vulkan layer configuration files.

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.

MANGOHUD_CONFIG parameters

You can customize the hud by using the MANGOHUD_CONFIG environment variable while separating different options with a comma.

cpu_temp : Displays current CPU temperature
gpu_temp : Displays current GPU temperature
core_load : Displays current CPU load per core
font_size : Changes the default font size (default is 24)
width : Set custom hud width
height : Set custom hud height
position=x: Available values for x include top-left, top-right, bottom-left, and bottom-right

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

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

Environment Variables

MANGOHUD_OUTPUT : Define name and location of the output file (Required for logging)
MANGOHUD_FONT: Change default font (set location to .TTF/.OTF file )

Keybindings

F2 : Toggle Logging
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.
