Does anyone have any thoughts as to why the Radeon VII which seems to be recognized across benchmark apps like Luxmark and Geekbench and by Profiler but will not accelerate FCPX. It seems to provide a bit of support but does not fill GPU History in Activity Monitor the way my RX 580 would show it was being maxed out. I am running 18,3 SMBIOS, 7700K, Gig Z170X gaming mobo. I tried SMBIOS iMacPro 1,1, turned of iGPU (it crashes otherwise) and FCPX flew, rendering was 2X faster than my RX 580 but no matter what I do I can't get FCPX to do the same thing in 18,3. Thanks.
