[Eric Johnson] “Do you have the “Use GPU for RED Debayer” checked in the Resolve settings”
Interestingly, when that is unchecked, the CPU maxes out and GPU goes to about 15%, but when it is checked, the CPU hovers between 60-75% yet the GPU stays around 15%, and there isn’t much of a playback difference between the two options.

Yeah, it does show up in Resolve under GPU:
And I am getting data in cuda-z:
Does that mean anything to you? To me it seems like the GPU is entirely functional but there is something I’m missing with Resolve. Perhaps a re-install would do the trick?

I will try all of the above, thanks!
I also used atMonitor to check my hardware usage and while playing back in Davinci, it was using 15% GPU and 75%+ CPU. Something is indeed wrong!—

Strange, I never got that warning.
I can confirm having cuda 7 and web driver enabled.
I don’t seem to have the Resolve options you mentioned, probably because I’m using Lite.I tried starting a new project with a Red file playing from an internal RAID and it still stuttered at Half Good, and stuttered the same amount at 1/16. Something about the GPU seems to not be kicking in, but only specifically in Resolve! Premiere uses CUDA fine but in Davinci, it’s running worse than my old ATI 5770.
Is there anything else you can think of?

Thanks for your input on the CPU—I plan on upgrading it down the line.
As for the 980 driver, what I have is the “QUADRO & GEFORCE MAC OS X DRIVER RELEASE 343.02.02f04” which is the latest Nvidia driver for Mac GeForce cards. Naturally, the GTX 980 is not in the supported products list since it is not available for Mac. Do you have any suggestions on getting a driver for Mac that includes the 980? It was my understanding that Yosemite supported it natively. I’d appreciate any help you could provide!

Thank you Paul!
I just confirmed that I do have the latest drivers from Nvidia and for CUDA, but that didn’t seem to change the performance. Strangely, Premiere CS6 recognizes the card and can take advantage of CUDA acceleration, but Resolve still seems to be at a near-standstill.
I’ve seen a lot of posts that use the Unigine Valley Benchmark tests—would that help to prove that my card is working as it should?

Thanks so much, this has been a huuuuuge help!

Out of curiosity, do Mac Pros come with MiniSAS technology or is that something I need to expand via PCI slot? Is there some kind of SAS controller card or is there a component inside that I’ve missed?
Thanks!

Hey Alex, thanks for the quick reply!
Since we’ll be going through a lot of projects, maybe an internal RAID0 would work out fine, and just swap out new drives per project?
I see that Thunderbolt and USB are a dead end!
[Alex Gerulaitis] “How fast is “fast enough”? :)”
Haha, I actually am not entirely sure WHAT to ask about PCI slots. I have heard that they can be expanded and utilized for storage solutions but I have nooooo idea what’s out there and how it works. In this case I guess it would be relative speeds between an internal RAID0 with the hard drive bays vs whatever the heck is possible with PCI slots.
Any clarification is greatly appreciated!

Thanks for the quick reply! I would really love to get more practice but there’s a very tight deadline and I also have some other post assets to manage before then. I did get exactly the look I needed with the Camera Raw sliders so I’m really hoping there is a way for Resolve to read those changes, short of exporting a whole new image sequence!
Thanks for the advice though, once the project is done I plan on practicing to match the color work done in Raw 🙂
