@mac_editor, thx but actually selecting my eGpu 6900xt for share and rendering is not improving that much. Cause most of the job is still made by the internal Gpu.

And when I do render or share with final cut using the 6900xt, it never go higher than 15-20% of the eGpu processing.

that’s why my question was how to use your script set-eGpu with Big Sur, so my 6900 will the go to Gpu for all the fcpx processing, instead of having my internal used for playback and most of the processing fcpx need, and the 6900 just for rendering and share with a super low % of power used.

 

thx a lot for your feedback.

@boulawayne, this script won’t help you with that. FCP handles gpus itself since the update. You can try to figure out the underlying process that’s doing the encode and see if eGPU preference can be set for that. I haven’t investigated personally.

@mac_editor,  was excited by your finding including your previous comments on how to eGPU accelerate apps under Mojave.  This would have also been huge news in the Hackintosh community if it worked.

Though no success so far.  Using your method,  I was unable to get FCPX to be eGPU accelerated. Nor did Valley/Heaven accelerate if launched from the iGPU-attached LCD as has been reported here.

Only difference is my RX580 reports as discrete (PCIe not Thunderbolt) device, plus it's not "removable".  The reports here have been mostly with Nvidia TB eGPUs.

If you have any suggestions, please advise. I was however able to get FCPX acceleration by booting up with the eGPU as the primary video device, with iGPU disabled. So only one LCD active there.

A few years late, but it should be possible to now direct apps to launch on a specific GPU: https://egpu.io/forums/mac-setup/launching-apps-on-specific-egpus-on-macos/

This also means users using M.2 (or Mac SSD slot) eGPUs can somewhat control GPU behavior, and so, it should be applicable on Hackintosh setups.

Hmm... that's strange. 😕 

Although I'm using Catalina which may be the difference, I have no problem using the script to accelerate applications including FCPX.
