+@section occt_debug_macro Compiler macro to enable extended debug messages
+
+Many OCCT algorithms can produce extended debug messages, usually printed to cout.
+These include messages on internal errors and special cases encountered, timing etc.
+In OCCT versions prior to 6.8.0 most of these messages were activated by compiler macro *DEB*, enabled by default in debug builds.
+Since version 6.8.0 this is disabled by default but can be enabled by defining compiler macro *OCCT_DEBUG*.
+
+To enable this macro on Windows when building with Visual Studio projects, edit file custom.bat and add the line:
+
+    set CSF_DEFINES=OCCT_DEBUG
+
+Some algorithms use specific macros for yet more verbose messages, usually started with OCCT_DEBUG_.
+These messages can be enabled in the same way, by defining corresponding macro.

 In real-world applications modeling operations are often performed in a long sequence, while the user sees only the final result of the whole sequence. If the final result is wrong, the first debug step is to identify the offending operation to be debugged further. Boolean operation algorithm in OCCT provides a self-diagnostic feature which can help to do that step.

+
+This tool maintains an array of 100 global performance counters that can be started and stopped independently. Adding a performance counter to a function of interest allows to get statistics on the number of calls and the total execution time of the function.
+* In C++ code, this can be achieved by creating local variable *OSD_PerfMeter* in each block of code to be measured.
+* In C or Fortran code, use functions *perf_start_meter* and *perf_stop_meter* to start and stop the counter.
+
+Note that this instrumentation is intended to be removed when the profiling is completed.
+
+Macros provided in *OSD_PerfMeter.h* can be used to keep instrumentation code permanently but enable it only when macro *PERF_ENABLE_METERS* is defined.
+Each counter has its name shown when the collected statistics are printed.
+
+In DRAW, use command *dperf* to print all performance statistics.
+
+Note that performance counters are not thread-safe.

 @subsection overview_req_graphics Graphic cards
 
-For 3d viewer, graphic card or software implementation supporting OpenGL 1.1 
-or above is required. OpenGL 2.1+ is highly recommended.
-For ray tracing, hardware implementation of OpenCL 1.1+ is required.
+On desktop, 3D viewer requires graphic card or software implementation supporting OpenGL 1.1 or above. OpenGL 2.1+ is highly recommended.
+Ray tracing requires OpenGL 4.0+ or OpenGL 3.1+ with GL_ARB_texture_buffer_object_rgb32 extension. Textures within ray tracing will be available only when GL_ARB_bindless_texture extension is provided by driver.
+
+On mobile platforms, OpenGL ES 2.0+ is required for 3D viewer. The ray tracing is not yet available on mobile platforms.
+Some old hardware might be unable to execute complex GLSL programs (e.g. with high number of light sources, clipping planes).
 
 The following table lists graphic cards tested to work with OCCT.
