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
