High CPU usage when using camera

[zalintyre]

Hello altogether,

since a few months, I'm experiencing an extremely high load on Zoom meetings when my camera is active. This leads to enormous lags and delays in both audio and video transmission in both directions.

This is my CPU load when the camera is turned on:

And this is the CPU load when the camera is turned off during the meeting:

This does not happen when either:

* The camera is muted in the meeting

* Nobody else is on the meeting

Since a few Zoom versions, there is a menu item "run with dedicated graphics card", which does not change anything regarding the CPU problem.

Hardware:

Lenovo P1 Gen2 / Intel(R) Core(TM) i7-9850H CPU @ 2.60GHz

Webcam: Logitech C920 HD Pro Webcam

Software:

OS: Ubuntu 22.04.2 LTS

GPU Driver: nvidia-driver-525
Zoom Version: 5.15.2 (4260) (Problem has been present for a few major versions)

Please advise.

Kind regards
Franz

Problem solved: There was a ton of dust inside the notebook and after cleaning up, the CPU doesn't get throttled any more...
