glmark2 - OpenGL (ES) 2.0 benchmark suite

       glmark2 was written by Alexandros Frantzis and Jesse Barker based on the original glmark by Ben Smith.

glmark2 2023.01                                   January 2023                                        GLMARK2(1)

       glmark2 offers a suite of scenes that can be used to measure many aspects of OpenGL (ES) 2.0 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  glmark2, 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.

glmark2  is  a  benchmark  for  OpenGL  (ES)  2.0.  It only uses the subset of the OpenGL 2.0 API that is
       compatible with OpenGL ES 2.0.

       To run the default benchmarks:

              glmark2

       To run a benchmark using scene 'shading' with a 'duration' of '5.0' seconds and
        'shading' of type 'phong':

              glmark2-bshading:duration=5.0:shading=phong

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

              glmark2-bshading:duration=5.0-bbuild:use-vbo=false-btexture

       To set default option values for benchmarks:

              glmark2-b:duration=2.0-bshading-bbuild-b:duration=5.0-btexture

       glmark2 - OpenGL (ES) 2.0 benchmark suite

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

       -f, --benchmark-file FILE
              Load benchmarks to run from a file containing a list of benchmark descriptions (one per line) (the
              option can be used multiple times)

       --validate
              Run a quick output validation test instead of running the benchmarks

       --data-path PATH
              Path to glmark2 models, shaders and textures

       --frame-end METHOD
              How to end a frame [default,none,swap,finish,readpixels]

       --swap-mode MODE
              How to swap a frame, all modes supported only in the DRM flavor, 'fifo' available in  all  flavors
              to force vsync [default,immediate,mailbox,fifo]

       --off-screen
              Render to an off-screen surface

       --visual-config
              The       visual      configuration      to      use      for      the      rendering      target:
              ´id=ID:red=R:green=G:blue=B:alpha=A:buffer=BUF:stencil=STENCIL:samples=SAMPLES'.   The  parameters
              may  be  defined  in  any  order,  and  any  omitted parameters assume a default value of '0' (id,
              stencil, samples) or '1' (red, green, blue, alpha, buffer).  If 'id' is set to a  non-zero  value,
              all other parameters are ignored

       --reuse-context
              Use a single context for all scenes (by default, each scene gets its own context)

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

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

       --results RESULTS
              The types of results to report for each benchmark, as a ':' separated list [fps,cpu,shader]

       --results-file RESULTS-FILE
              The file to save the results to, in the format determined by the file extension [csv,xml]

       --winsys-options OPTS
              A list of 'opt=value' pairs for window system specific options, separated by ':'

       -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)

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

       --annotate
              Annotate the benchmarks with on-screen information (same as -b :show-fps=true:title=#info#)

       -d, --debug
              Display debug messages

       --version
              Display program version

       -h, --help
              Display help
