I started today the dev of a PhysX 3 plugin for GLSL Hacker...

Links to Shadertoy demos available here:

Two short tutorials to quickly start coding with Lua and Python:

- Lua Primer for the Impatient

- Python Primer for the Impatient

Here are the main command line parameters included in GLSL Hacker:

• /fullscreen
      forces fullscreen mode.
• /demofile="filename"
      specifies the absolute path to the demo file.
• /benchmark_duration_ms=<n>   
      specifies the duration of the demo/benchmark in milliseconds.
• /benchmark_log_score   
      writes benchmark results in the benchmarl log file (CSV file).
• /benchmark_display_score_box   
      displays the score box at the end of the benchmark.
• /disable_opengl_support_check   
      disables the check of the OpenGL version done at the beginning of a demo.
• /noload_plugin_opencl   
      disables the loading of the OpenCL plugin.
• /noload_plugin_python27   
      disables the loading of the Python 2.7 plugin.
• /glinfo 
      writes OpenGL complete information (all OpenGL extensions) in the log file.
• /vbo_usage=<usage>
      forces vertex buffer usage: GL_STATIC_DRAW, GL_STATIC_READ, GL_DYNAMIC_DRAW, GL_DYNAMIC_READ, GL_STREAM_DRAW, GL_STREAM_READ.
• /ibo_usage=<usage>
      forces index buffer usage: GL_STATIC_DRAW, GL_STATIC_READ, GL_DYNAMIC_DRAW, GL_DYNAMIC_READ, GL_STREAM_DRAW, GL_STREAM_READ.

Example:
GLSLHacker.exe /demofile="C:/The/Path To/The/Demo.xml" /vbo_usage=GL_STATIC_DRAW /benchmark_duration_ms=5000 /benchmark_display_score_box

    Model identifier should be MacPro3,1 (2008), MacPro4,1 (2009), MacPro5,1 (2010) or later
    Mac OS X v10.8.3

New quick tutorial:

(the samples below, for some reason GPU test fails).

Maybe the failure is related to the fact that GPUTest is a 64-bit application? All other benchmarks (FluidMark, FurMark, ...) are 32-bit apps.

Yes, indeed!
The Kainy server software is only 32 bit, so it can't hook into 64 bit apps.
