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:

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

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

To set default option values for benchmarks and run them:

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