Cannot enable GPU acceleration in Final Cut Pro rendering and exporting

Hi guys,

just got from clover to OpenCore about a month ago. When I was on clover a few months ago I was able to enable hardware acceleration, now that I've "restarted" from OpenCore I can't find a way to make Final Cut usable. All the workload is on the CPU, none of it on the GPU. Does anyone solved recently a issue like this?
Sorry for the bad explanation, hope you'll understand.

Specs:

CPU: Intel i7 3770k

GPU: Radeon RX580 8gb

macOS Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina 10.15.3 OpenCore
