Summary
CPU usage is still too high, hovering around 85% with my camera ON during a Google Meet.
Details
THANK YOU for reducing CPU usage from 100% during Google Meet meetings to 80%! Tha'ts a very recent development, and a great improvement! However, that's still too high. Please lower it further.
Here is a CPU usage plot showing me in the Google Meet with my video camera ON vs OFF. Notice the HUGE change in CPU usage when my camera is ON:

I have 8 CPU hyperthreads.
Top processes (as logged by my cpu_logger.py script) with my camera ON while in a Google Meet
With my video camera ON, the overall CPU usage was 84.79%. This is still too high. I need to be able to run other things at the same time. Here is a snapshot of my top 10 processes at that time:
