Hi folks. Fairly new hackintosh, running Catalina. FCPX (latest version, 10.4.7) doesn't seem to be harnessing the power of my big ol' Vega 64. Can anybody help me get it rippin?
I spent a great deal of time trying to get both the iGPU (it's an i5 8400) and dGPU (PowerColor AXRX Radeon 64) working together. No dice. So I've given up on that and I'd be happy if FCPX would just work well with the Vega.
Everything else seems to be working fine with the Vega. Geekbench compute scores are nice and high. System Info reports the Vega 64 properly. FCPX runs just fine for editing/skimming/etc. It's just that the exports are SUPER slow.
Oddly, the BruceX export benchmark is really good. I get it done in about 16 seconds. And when the BruceX export is running, the Vega does show it's being used through Activity Monitor, although it never really goes beyond about 50% utilization.
BUT, if I try to export a "real world" project using H.264 or ProRes or 422, the CPU cores all show 100% utilization, but the Vega does absolutely nothing. As a test, I've got the exact same project on my 2015 MacBook Pro. The MacBook's built-in Radeon M370X completely maxes out on export, as well as using the iGPU, and it's wiping the floor with my Hackintosh and its unused Vega 64.
Is there some magic setting I'm missing? I've dropped my EFI folder in drive for y'all to look at.
The hardware specs:
CPU: i5 8400
MoBo: MSI z370-A Pro (I have a suspicion this mobo is what's preventing me from getting iGPU+dGPU to work, since its DVMT is limited to only 64MB for some reason.) But I really don't know.
GPU: PowerColor AXRX Vega 64
