NAME

       mangohud - enable MangoHud on any application

SYNOPSIS

       mangohud [--dlsym] COMMAND

DESCRIPTION

       MangoHud is a Vulkan/OpenGL overlay for monitoring FPS, temperatures, CPU/GPU load and more.

USAGE

       MangoHud can be enabled for Vulkan applications by setting MANGOHUD=1 as environment variable.
       To load MangoHud for any application, including OpenGL applications, the mangohud executable can be used.
       It preloads a library via ld into the application.
       Note: some OpenGL applications may also need dlsym hooking. This can be done by passing option --dlsym or
       by setting MANGOHUD_DLSYM=1 as envrionment variable.

CONFIG

       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:

           /path/to/application/MangoHud.conf
           $XDG_CONFIG_HOME/MangoHud/{application_name}.conf
           $XDG_CONFIG_HOME/MangoHud/MangoHud.conf

       An example config file is located  in  /usr/share/doc/mangohud/MangoHud.conf,  containing  all  available
       options.

       A custom config file location can also be specified with the MANGOHUD_CONFIGFILE environment variable.
       Config  options  can  also be set with the MANGOHUD_CONFIG environment variable. This takes priority over
       any config file.

EXAMPLES

       OpenGL: mangohud glxgears
       Vulkan: MANGOHUD=1 vkcube
       Steam: set your launch option to mangohud %command%
       Lutris: add mangohud to the Command prefix setting
       OpenGL with dlsym: mangohud --dlsym glxgears
       Custom config options: MANGOHUD_CONFIG="gpu_stats=0,font_size=12" mangohud glxgears
