Asking help for one possible extension

[spaul13]

First of all great work done. Just from general curiosity, from best of my knowledge, the CPU is dumping commands inside the GPU driver (command buffer) and GPU is taking instructions for rendering from the driver.

Is it possible to know (using this plugin or modifying the RenderTimingPlugin?cpp whats the frequency of reading out commands by GPU from the buffer and the frequency of CPU writing inside the buffer?

Any sort of hints or help regarding this will be highly helpful.
