I may have found something…

I was about to take my machine in to Apple for service, but before doing so I thought I’d try running Premiere in a ‘clean’ user account.

So I made a new (admin) account, copied over some project files, and launched Premiere.

I set the project to CUDA, started ‘working’, and immediately noticed some differences: playback would start much faster, rendering started faster, less jerkiness in playback. And I was not getting any of the glitchiness. I had other issues besides the glitchiness, like clips dropped in dynamically from Ae would not update unless I manually switched over to Ae, and these things went away.

I didn’t really spend several hours actually working, but it seems much smoother. Made me think the issue was due to ‘gunked up’ settings etc over months of work.

So I (backed up and) wiped my drive, clean installed Yosemite (I was on Mavericks before), set up CC etc. But after copying over all my settings, including downloading settings from Adobe, the performance was twitchy again. Bummer.

I created a fresh account again, and again, in the new account, Premiere performed much better. Even complex speed ramps and Ae clips played back incredibly fast in real time, better than I’ve seen in months.

I won’t know for sure until I spend a day editing, but it might be that a lot of these issues stem from corruption or some kind in the user settings.

So I went back to my original account, and deleted EVERYTHING with the word ‘adobe’ or ‘premiere’ within my User folder (including ~/Library and ~/Documents). The performance is now similar to that of the ‘clean’ account.

So far it’s working rather well … I will report back after spending more time.

Maybe some other can test this out and report back … try a fresh account, and if you notice a difference, go back to your main account and delete (or put aside) all the Adobe stuff in your ~ folder. DO NOT SYNC SETTINGS from Adobe servers.

If, like me, you absolutely need your custom keyboard shortcuts, you can manually copy the .kys files from
~/Documents/Adobe/Premiere Pro/8.0/Profile-CreativeCloud/Mac/

So how do we start a class action suit against Apple?
Seems like the only way to get them to do something.

Might be good to stay in one place…

Hi,

There is an active investigation into these reports ongoing in conjunction with Apple and Adobe, but I don’t have any specifics on the root cause or when a fix might arrive.

Actually, from what I’ve gathered, speaking with nvidia, as well as watching my GPU usage monitor (iStat Menus),
OpenCL *does* use the GPU, but less efficiently.

Do a test of OpenCL vs Software-Only and see what you get. It should be considerably faster.

[Ze’ev Gilad]

I also have no problem if I use OpenCL. I thought that wasn’t the issue here.
The problem for me is with CUDA, which, when it works, is much faster.

Or are you saying you switched to OpenCL then back to CUDA and it’s working?

[Ze’ev Gilad]

Does anyone know how to best cause this to happen so I can show the tech when I go to Apple Store?

[Ze’ev Gilad]

Rarely outside of Premiere … and not at all since I stopped using CUDA (just OpenCL) – but renders/exports are significantly slower.

[Ze’ev Gilad]

I’ve spoken, at length, to Apple, Adobe, and nvidia, all pretty much to no avail.

I am wondering … is it that my GPU is defective, or that this combo simply cannot work?

I’d like to know who is NOT experiencing this issue, and if any of them have the same setup that I do; but obviously those lucky people won’t likely find their way to this thread!

Apple said bring it in for repair, but that’s impossible, because I use it for work every day.

I have all the symptoms listed on that page, but my machine is a MacBook Pro (Retina, 15-inch, Mid 2014)
