I have dual graphics,

And, they are both inbuilt. The Radeon Pro 560X comes up when needed, and that need is decided by the MacBook/MacOS, as the need arises. I have Automatic graphics switching enabled. No problems whatsoever.


I heard some people's MacBooks have problems with internal dual graphics, so disabling the "Automatic graphics switching" would got rid of the problem(s) sometimes. I see you have an external GPU, and I don't know how MacOS takes care of that. I cannot find a 2020 13" MBP with dual graphics in the internet, to find out how that works.
