Evidently I didn't look hard enough... I found what I was looking for:
The NVPerfKit counters.
http://developer.nvidia.com/object/nvperfkit_counters.html. Do the
stats you refer to come from these counters or this type of feedback
mechanism? i.e. low level counters inside the hardware and driver?
Hi, Ed,
OSG uses the EXT_timer_query OpenGL extension to measure the GPU time
(all of the other stats are measured on the CPU). The EXT_timer_query
extension works with any Nvidia driver, whereas the NVPerfKit counters
require Nvidia's instrumented drivers, which most users won't be using.
