Question

macOS GPU Acceleration issues

Hi all!

My system looks like this:

macOS Mojave 10.14.5

MacBook Pro 15-inch, 2017

2.8 GHz Intel Core i7

16 GB 2133 MHz LPDDR3

Radeon Pro 555 2 GB

Intel HD Graphics 630 1536 MB

Adobe Premiere Pro 13.1.12 (Build 9)

Adobe Media Encoder 13.1 (Build 173)

I constantly have issues with the GPU Acceleration (both Metal & OpenCL)

These issues appear:

- Motion keyframes not respected

- Adjustment layers flicker

- Colors shift

- Opacity is affected

Reinstalling Premiere & Encoder, clearing Media Cache, restoring default settings, reloading plugins, deleting rendered files & previews didn't solve the issue.

I've now opted to switch to Mercury Playback Engine Software Only while working on projects but would like at least to be able to render using the GPU.

I understand MacBooks get driver updates via macOS upgrades (none available at the moment).

What else could I try? Do you have any ideas?

Thanks in advance!

That onboard processing chip isn't the same thing as a full GPU, so it's not going to be as useful as a full, dedicated GPU card.

And even among dedicated GPU cards, you need realistically at least 4GB of vRAM on the card for Premiere to find it of use.

It's far better than not having it, but ... well, it ain't a full GPU either.

Hi Neil,

Thanks for your input!

I understand a better computer could solve the issue
Nevertheless, are there any tweaks that might be worth trying with this one?

Cheers,

I'm not that familiar with Mac hardware, so hopefully someone else can offer ideas.

I know there have been troubles with some laptops where Pr gets kinked up between the onboard Intel graphics and the separate GPU. In your case, the GPU doesn't have enough vRAM to be really used by Premiere. So software-only may be your only solid method of working.

And I'd suggest using proxies made by the included Cineform proxy preset ... may help general performance some.
