I updated to fcpx 10.4.7 and Catalina. They changed the options where you select egpu usage, but it now seems that on my 2018 Mac mini, fcpx won't use the egpu for exporting. It will use the Intel UHD 630 no matter what. If I let it background render, it will use my egpu (Vega 64), and will use it for playback in the timeline, but as soon as I try to export anything it used the igpu. This wasn't the case on 10.4.6 … is this just an apple bug? will it be fixed in an update?
