NAME
glmark2 - OpenGL (ES) 2.0 benchmark suite
SYNOPSIS
glmark2 [options]
DESCRIPTION
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.
OPTIONS
-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
BENCHMARKS
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.
EXAMPLES
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 -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
