Yes. I have been using 2020 with the eGPU with no issue until I went to Catalina. Now if I do any movement in the drawing there is 0% gpu use on any of the cards and the CPU skyrockets.

Hugh The same thing is happening with me on my Macbook Pro. Chipset Model: Radeon RX Vega 64 External Chipset Model: Radeon Pro 560X Internal I am on VW 2020, just upgraded OS to Catalina, and VW will not use ANY GPU if i have the external plugged in. If I unplug it and only use the internal, VW functions great. I have been using VW since 2012 and had an external GPU since late 2018 without issue. Haven't found anything indicating a problem other than a few posts on this forum. VW tech support didn't have any suggestions other than to call Apple yesterday.

I'm stumped, any ideas? My crash log is attached. Thanks VW CRASH.txt
