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

By Roy Osherove August 18, 2020

(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](https://osherove.com/trainingoptions) about TDD:

1. Go into zoom settings

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

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

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.
