bugle-stats_nv - gather performance data from NVPerfSDK
flush " yes"
The stats_nv filter-set extracts data from certain NVIDIA GPUs using NVPerfSDK.
This filter-set is only built if the appropriate header file is present at
compile time, and also requires a suitably configured driver and GPU (refer to
The possible statistics can be seen in the example statistics file
(doc/examples/statistics in the bugle source distribution). It is important to
read the NVPerfSDK documentation to understand what the different types of
statistics are, what they mean, and the limitations of the hardware interface.
If set, a glFinish(3) will be issued immediately
prior to sampling the counters. This guarantees that events will be accounted
to the correct frame, but will cause pipeline stalls.
Because NVPerfSDK operates across OpenGL contexts, it will count events from
outside the debugged application. In particular, using
(7) to view the results will alter the statistics.
