How to get eGPU HW acceleration in Final Cut Pro X

[sarkrui]

The EFI posted in the release does not support eGPU HW acceleration in FCPX (though it's supported in DaVinci Resolve). Also, as I mentioned in the Not Working section, Thunderbolt 3 eGPU Hotplugging isn't working well on NUC8 (or most PC motherboards, except the Gigabyte x299 series).
One solution I found to get eGPU HW acceleration in FCPX is to use a headless ig-platform-id. To achieve that, you could could inject key framebuffer-portcount with a value 0 in the type of number under your config/device/properties (see snapshot).

Then,

• Your HDMI port will be disabled.
• Therefore you need to connect your monitor via eGPU.
