SOLVED - High CPU and Lagging when Screen Sharing in Zoom 2020 Multiple Screens

(on a mac)

I’m sharing here what I’ve learned the hard way. This has now helped me when teaching half day remote classes about TDD:

  1. Go into zoom settings

  2. Under “Screen Share” -> Advanced -> Screen Capture Mode

  3. Set Screen Capture Mode to “Previous Operating Systems”

Zoom settings on mac High CPU Usage

Also: You might also want to set “Limit your screen share to 8 frames per second” but it has worked well for me without it. even when live-coding, both sharing a screen and an individual app.

Solved - Pihole FTL DB is huge taking too much disk space
