I have a Raspberry Pi 3 Model B and would like to know how busy the GPU gets when I run certain tests to determine whether it would be possible for me to do certain things. I see that the GPU is a bit old (2014) as per:

https://www.raspberrypi.org/forums/viewtopic.php?t=106901

What I'm after is something similar to what nVidia offers in their settings window showing a % of usage of the GPU. I don't expect a nice graphical tool, but a way to access that type of info somewhere would be fantastic!

  • @Fabian, it looks like we don't have access to any info (as per that other thread) and that probably did not change sine 2013?

    @Fabian Also I see that the other question was more about "the split" (how much RAM is used by one and the other) rather than the CPU/GPU usage. Mine is clearly (I think) about the % usage of the GPU so I can get an idea of how much horse power I'm using and how much is still available for improvements to my software.
