Hello,

I have tried Gem on the Pi3 and it works. I did not try Gem completely because I had no time, but did not encounter major issues other than video capture. I could not use video capture since it overworked the CPU. However, accessing the video feed with openCV (not through Gem) gave very reasonable CPU usage (while doing Face Tracking, for example). I am not sure why I encountered such a difference, but I just couldn't use Gem for that.

Cheers,

Fede

i think this is the wrong question.

Gem on the rpi is kind of limited as it (Gem) depends on openGL and the
rpi provides openGL-ES (though there *are* experimental (still?) drivers
for openGL as well).
this is quite independent of purr data, pd-vanilla or whatever.
