       glmark2 - OpenGL (ES) 2.0 benchmark suite


       glmark2 [options]


       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.


       -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)

              Run a quick output validation test instead of running the benchmarks

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

              Render to an off-screen surface

              The     visual     configuration    to    use    for    the    rendering    target:
              ┬┤red=R:green=G:blue=B:alpha=A:buffer=BUF'. The parameters may  be  defined  in  any
              order, and any omitted parameters assume a default value of '1'

              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)

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

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

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

              Run indefinitely, looping from the last benchmark back to the first

              Annotate  the  benchmarks  with  on-screen   information   (same   as   -b   :show-

       -d, --debug
              Display debug messages

       -h, --help
              Display help


       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.


       To run the default benchmarks:


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

              glmark2 -b shading:duration=5.0:shading=phong

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

              glmark2 -b shading:duration=5.0 -b build:use-vbo=false -b texture

       To set default option values for benchmarks:

              glmark2 -b :duration=2.0 -b shading -b build -b :duration=5.0 -b texture


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