Thank you for your interest in an issue that's killing me! Applied the patch; it seems to always show cpu 16. I have an 8c/16t so it is shown fine. I attach cpu-count.txt to show output during playback and rendering operations. A video of the above operations can be found at the following address. https://www.dropbox.com/s/m4bpa0y9mk55btq/cpu-test.mov?dl=0 Note that today it went better than the average I normally have: in playback I had less freezes and in rendering I got an average of 60 fps, while normally I stay on 12 fps. Last note: from a 10 years ago laptop with a good i7 4c/8t I switched to an AMD 8c/16t with double the frequency. For example to compile CinGG (with all 8 threads in Intel and with all 16 threads in AMD, always at 100%) I went from 20 min to 5 min. Instead in playback and rendering I don't notice big differences. Using a rendering via handbrake or ffmpeg from command line is extremely more efficient.
