DaVinci Resolve 17 playback choppy

[Rabber]

Just started using Resolve 17 and have a choppy playback issue. I have an iMac 3 GHz 6-Core Intel Core i5, Radeon Pro 560X 4 GB I viewed several youtube videos to "resolve" this issue, however none of them worked. ?????

Watch this video and use the suggested settings. You will be surprized just how well it works then.

Thanks man. This was a great video. I watched several videos that had all kinds of complex solutions that did not work. Watched this video and changed ONE setting from 5 seconds to 1. Problem solved!
