NAME

       vkmark - Vulkan benchmark suite

SYNOPSIS

       vkmark [options]

DESCRIPTION

       vkmark is an extensible Vulkan benchmarking suite with targeted, configurable scenes.

OPTIONS

       -b, --benchmark BENCH
              A benchmark to run: 'scene(:opt1=val1)*' (the option can be used multiple times)

       -s, --size WxH
              Size of the output window (default: 800x600)

       --fullscreen
              Run in fullscreen mode (equivalent to --size -1x-1)

       -p, --present-mode PM
              Vulkan present mode (default: mailbox) [immediate, mailbox, fifo, fiforelaxed]

       --pixel-format PF
              Vulkan pixel format (default: choose best)

       -l, --list-scenes
              Display information about the available scenes and their options

       --show-all-options
              Show  all  scene option values used for benchmarks (only explicitly set options are
              shown by default)

       --winsys-dir DIR
              Directory to search in for window system plugins

       --data-dir DIR
              Directory to search in for scene data files

       --winsys WS
              Window system plugin to use (default: choose best) [xcb, wayland, kms]

       --winsys-options OPTS
              Window system options as 'opt1=val1(:opt2=val2)*'

       --run-forever
              Run indefinitely, looping from the last benchmark back to the first

       -d, --debug
              Display debug messages

       -D, --use-device
              Use Vulkan device with specified UUID

       -L, --list-devices
              List Vulkan devices

       -h, --help
              Display help

BENCHMARKS

       vkmark offers a suite of scenes that can be used to  measure  various  aspects  of  Vulkan
       performance.  The  way  in  which  each scene is rendered is configurable through a set of
       options. To get the available scenes and their acceptable options  you  can  use  the  -l,
       --list-scenes command line option.

       In vkmark, a benchmark is defined as a scene plus a set of option values.  You can specify
       the list and order of the benchmarks to run by using  the  -b,  --benchmark  command  line
       option  (possibly  multiple  times).   If  no  benchmarks  are specified, a default set of
       benchmarks is used. If a benchmark option is not specified it assumes  its  default  value
       (listed with -l, --list-scenes).

       As  a  special case, a benchmark description string is allowed to not contain a scene name
       (i.e. to start with ':'). In this case, any  specified  option  values  are  used  as  the
       default values for benchmarks following this description string.

EXAMPLES

       To run the default benchmarks:

              vkmark

       To  run  a  benchmark  using  scene  'vertex'  with  a  'duration'  of  '5.0'  seconds and
       'interleave' set to 'false':

              vkmark -b vertex:duration=5.0:interleave=false

       To run a series of benchmarks use the -b, --benchmark command line option multiple times:

              vkmark -b vertex:duration=5.0 -b clear:color=1.0,0.5,0 -b cube

       To set default option values for benchmarks and run them:

              vkmark -b :duration=2.0 -b vertex -b clear -b :duration=5.0 -b cube

       To set default option values for the default benchmarks and run them:

              vkmark -b :duration=2.0
