To add: OBS can output to v4l2loop so can feed as virtual camera.
And OBS has lots of neat features - one of which is making my fans loud. Like a crowd cheering it on!

Especially, if you use the Zoom desktop client. Zoom on web (Firefox) seems to be easier on the CPU for some reason though.
Going forward, I wonder if OBS will offer pipewire or gstreamer streams (if those are a thing) for consumption by other apps?
Dedicated recording apps for cameras and screens will give you better performance and occasionally a marginally better image since there are fewer steps in the pipeline.
For v4loopback, a short gstreamer pipeline (for those willing to use the CLI) will perform better and give you noticably lower latency - even if some basic cropping is required, like if you're using a capture card with a camera that you can't hide the UI on.
You're likely using software encoding. My 2015 MBP has a GT750M, but "thanks" to Apple OBS can't use hardware acceleration (https://obsproject.com/forum/threads/question-about-hardware...). Situation on Linux is likely similar.
