| '''OpenGL extension AMD.performance_monitor |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.AMD.performance_monitor to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension enables the capture and reporting of performance monitors. |
| Performance monitors contain groups of counters which hold arbitrary counted |
| data. Typically, the counters hold information on performance-related |
| counters in the underlying hardware. The extension is general enough to |
| allow the implementation to choose which counters to expose and pick the |
| data type and range of the counters. The extension also allows counting to |
| start and end on arbitrary boundaries during rendering. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/AMD/performance_monitor.txt |
