I am very interested in the the GPU utilization of my app, so I try to capture it with "Process -> GPU general -> GPU % Utilization" and "System -> GPU general -> GPU % Utilization" .
The screenshot of the observation is shared with following google drive link.
What confused me is that the reading "GPU % Utilization" from process and system are quite hard to understand.
First, why the process "GPU % Utilization" reading is like 27.49G and 17.75K (as shown in the pic)? What do numbers with G or K mean here? why is it not a percentage number like what shown in system "GPU % Utilization" reading?
Second, why the system "GPU % Utilization" reading is always 100%?
BTW, I am using Nexus 6p with Android 7.1.1
Thanks in advance.
