Zoom makes my 12 core CPU burn to the ground. I wonder if it's the camera. Some cameras do some processing in hardware it seems, but I suspect this happens only with proprietary drivers (probably not on linux).
Not a hardware solution but it's being talked about today, I wonder if using OBS to capture the video and outputting it to v4l2 loopback with https://github.com/CatxFish/obs-v4l2sink and reading it in zoom that way would be better. Just a thought, hope this helps.
I haven't checked today, but on Monday I was able to buy a webcam directly off of Logitech's website. All the retailers I could think of checking were out of stock.
I haven't been able to use my webcam lately because the teleconferencing I use (WebEx and Slack) is having issues keeping up with bandwidth. I haven't even been able to use the On Computer audio and had to dial in.
