Well, if the fans are spinning, it heats up, power is drained, and the CPU usage is fine... it's gotta be the GPU. There's only so many things in the system that can use power and generate heat, after all. I don't know enough about MBPs of that age, but I'd guess they have discrete GPUs and it's those are running. I wonder if you'd be better off disabling GPU optimizations, or if there's a codec issue of some kind. https://developer.mozilla.org/en-US/docs/Web/Media/Formats/WebRTC_codecs https://developer.mozilla.org/en-US/docs/Web/Media/Formats/W...
