Hi @pastrychef

I write here as you've this thread and have come across lots of things.
I have an issue on an Asus Prime Z370-A II and Final Cut Pro.
It's not about rendering, that works great as everything else but one thing:
The issue is memory related. Basically Final Cut Pro consumes huge amounts of memory.
Even just importing video files into a library, for example 60GB of files, you easily get Final Cut Pro to use 140GB of memory. Once that begins to happen obviously the app and the system begin to become unresponsive.

On my Asus Rog Strix Z370-I Gaming if I import the same type of files (Sony Alpha) it's all fine and smooth. FCPX takes 800MB of Ram.
I tested a different MacOS Mojave installation but the issue is still there.
It's some sort of memory leaking and the app becomes unusable after a while.

Have you ever come across any similar issue in Mojave?
Could it be a Bios version?

Thanks a lot.

It may be related to the transcoding and optimizing files process Final Cut uses. As a test, try turning it off (in Preferences) and see if your system stabilizes. That may help you narrow things down.

One guess... your graphics card configuration and how it interacts with that process. On the system that is working, what type of graphics card does it use?

Hi, thanks for your reply.

On the system that works I use a RX 570 4GB Mini.
On the system that doesn't work I use a RX Vega 56 8GB.
Final Cut Pro both without any SSDT for the Vega or with an overclocked SSDT has the memory leak.

As you can see from the attached image, all those transcoding options are switched off.

Do you mean Background Render?
Settings are the same in the two Final Cut Pro I use.

Today I switched Bios on this Asus Prime Z370-A II but it made no difference.

Do you have IGPU enabled? Have you tried with IGPU disabled and using iMacPro1,1 system definition?

I haven't tried this option.
I can try SMBIOS iMac Pro.
At the moment I run SMBIOS iMac 19,1. I tried SMBIOS iMac 18,3 but the issue persists.

As a side note, this issue happens only during import. After that the app runs fine.

So after the import, you RAM frees up??

So for both optimize media and background render, the system is doing transcoding. Background render is a constant process as you probably know...so for every change to things like color, effects, transitions, etc., it's rendering a new file.

Your two video cards use the Mac hardware differently for both of those processes...one works with the internal graphics (RX 570) to speed rendering, the other is stand alone (RX Vega)...at least that's my understanding.

In BIOS is your internal graphics on? What about the other system?

I think Pastry is on the right track by asking about your system definition. That would impact how the Vega renders.

You could test the theory a few ways...turn off background render and see if it calms the memory leak. Or, switch graphics cards between the systems. Or try definition 1,1.

The import of 58GB of files leads to 140GB of Final Cut Pro memory usage. All hangs up.
If I import smaller numer of files I have to close Final Cut Pro to free up the memory.

Background render is switched off as all the transcoding options during import.
A split second after you open Final Cut Pro and click import you can see the memory consumption of the app in Activity Monitor spike to 20GB. It takes a couple of seconds.

In both systems iGPU is turned ON.
The system that has the memory issue also has Windows 10 Pro on a second SSD. In Windows Edius wants the iGPU turned ON.

Background render is switched OFF.
SMBIOS 18,3 and 19,1 both show the same memory issue.

I'm left with testing iMac Pro with iGPU turned OFF.
 
@pastrychef do you know how to we find new type firmware for BiosVersion on OC? I checked your files and you are using old type BiosVersion? On doc says BiosVersion changed with OC. is that mean BiosVersion equal to EFI Version?
