Curious about those who have Final Cut X and HEVC export working well on Catalina. What setup are you using?

On my system (SMBIOS Mac 1,1 - iGPU disabled) FCX, Quicktime, and Compressor take FOREVER to export clips despite having a 9900K process and Radeon VII graphics card. A 10 second clip takes nearly a minute. Previous MacOS and FCX versions were fine. Clips exported in near-real time or faster.

H264 is fine. And strangely, Premiere Pro exports HEVC well.

Any thoughts?
