zoom requiring 30-40% CPU without video?

[ghanwani]

Why does zoom require 30% CPU (occasionally spiking to 40%) without video? I find my machine heating up whenever I'm on a call. This is on a 2019 13" 2.4 4TB model.

It's pillaging all your data in the background.

No, not sure, but that does seem incredibly excessive if it's just digitizing voice.

It runs fine on my 2015 MBP 15. I find that it doesn't take a lot to get my 2015 MBP 13 fans running - YouTube and something else will do it. But your laptop should be a lot more efficient.
