Proof FCPX 10.4.7 is slower than 10.4.6 and eGPU use worse

I really don"t understand what's going on, just restarted Capture One Pro(RAW photos software) and I works fine and way better than without eGPU, and I tried with Call Of Duty Black Ops III and the Vega and only that is used......FCPX dev need to work on this issue.

Im telling you man, go back to 10.4.6 and select prefer eGPU and see how FCPX then FULLY uses eGPU, 4.7/4.8 it messes up, your only choice is to go back 4.6 till they fix it, else move on to Premiere/Resolve. And DONT listen to all that "External monitor plugged here plugged there etc etc" BS, this is a real problem against anyone else who says. Also call up FCPX team and tell them, the more of us call the better chance they'll fix it

The thing you have to realize is that Apple has suggested using these external eGPU's also for any application besides just gaming. They have a whole page dedicated to which ones work and which graphics cards are supported. I purchased a Radeon Vega 56 and the OWC Mercury Helios FX 650 to hook into my 2017 iMac and it performed very nicely up until 10.4.6. I just purchased the brand new 16" MBP with everything but the HD maxed out (2.4 8-Core, 64GB RAM, Radeon Pro 5500M 8GB card) and the thing screams speed. I haven't tested benchmarks yet between this graphics card and the Vega 56 or 64. But my feeling is that Apple will fix what ever is the problem but who knows when is the main issue.

Can you give me a link to where Apple says that?

You macbook pro will not benefit from an eGPU you have 8 GB of video ram, apple developer guidelines say to prefer the discrete gpu because PCI bandwidth is much higher than thunderbolt so it is likely it does not even call it at all except background rendering when you have the screen on.

Your iMac 2017 depending on graphic card will also have no benefits for the same reason above

It is possible that with Open CL the situation was better and now that final cut pro is re-written for metal is worse but there are plenty of independent tests that show that an average discrete gpu performs better than an eGPU on final cut pro in any release which is what the poster of this thread wrote himself.

The “commenter” is the one whose coming in this thread (don’t know why since he doesn’t have the same issue we have) and telling you and everyone else the problem is with us not the software. Don’t waste your time just ignore him. Like I said this is a real issue, I went back to 10.4 6 and the issue is gone eGPU is fully working and amazing. Talk to Apple and follow up that’s what we’re all doing ( except for you know who)

Great post, I can't believe Apple have ignored this issue for so long. I'm now pushing for a refund on my (now) useless hardware that I bought from them and the egpu hardware.

My issue is that projects that took 4-5 mins to render in 10.4.6 now take 30 mins in 10.4.7 + on the same hardware, and the same project.

Apple sold the Mac Mini to be used with egpu's, now all of that info has dissapeared (conveniently) from Apple's site but it's there, use Time Machine.

Also look at the plethora of video's showing how much an egpu increases the render times on a Mac Mini.......2 Such as:

The argument that there is no problem, as one of the commenters on here keeps harping about, ( don't know why he's in this group if he sees no problem) is redundant. Im using 4.6 and it works fine, since I downgraded from 4.7/8 If a judiciary recourse is what it takes then we'll need to do that. I just don't see why Apple doesn't give it the same optional feature they have on the 4.6?

This is the physical apple support page about eGPU's and their usages with Thunderbolt 3 Mac computers.

Hi Tom,

If you only have one monitor attached to a MacMini & eGPU, you don 't get an arrangement tab as shown below...

Is the display attached directly to the external GPU box or to the mac mini?

Thanks. I wasn’t sure if a tab would show up for the eGPU.

Just checking that you're selecting your eGPU in the FCPX preferences. (Final Cut Pro -> Preferences -> Playback -> Render/Share GPU)?

This has unfortunately not worked for me. I did this and even tried totally disconnecting the external monitor but it seems FCP won't make use of my VEGA 56 eGPU at all on 10.4.7.

Please use feedback to report your problem in as much detail as you can fit.
