How to extract counter data displayed on TGD performance dashboard

Hi,
I bought K420 device and installed TGD to see GPU behaviors more detail.
Through performance dashboard in TGD, I could see GPU counter movements just as graphs.
Is there any way to extract counter data displayed on TGD performance dashboard and store them into a file?

yes, you need

  1. capture frame
  2. open profiler view,
  3. select summary -> counters
