METAL or CUDA better for GPU Performance...

Running a Hackintosh system on Davinci Resolve 14 with NVIDIA GTX 1080Ti 11GB Graphics Card with 64GB Ram and 4.01 GHz Intel Core i7....


Which GPU Processing Mode is better OpenCL or CUDA or Metal?

Definately not OpenCL as you have a CUDA Nvidia card. For me OpenCL even gave lots of broken graphics artefacts etc and Resolve crashes.
So normally CUDA as thats what your card is designed for.
You could play with metal and your mileage may vary. For me on my hack it was way slower then CUDA but faster then OpenCL.

Just run some test yourselve and try them all

No idea about Resolve, but in PP I'm getting at least the same performance and no/less render errors. Running a 2015 rMPB.

I'd be curious to know your results after testing all three with the 1080 Ti. Rendering times to be exact. Plus which rendering time correlates when 'Auto' GPU Processing is selected.

Thank you

I suppose very soon you'll be better off with Metal 2 on original Macs, since they stick to AMD recently.
But I doubt they'll do much for Nvidia, as long as there are only heritage or Hackintoshes with those.

When I rendered 1 Minute Red R3D 6K File from Dragon these are results:

GPU Processing Mode AUTO - 05:56
GPU Processing Mode CUDA - 05:43

Attached screenshot...

Interesting, a 4% increase in render time with CUDA.

Did you run the render test more than once?

I have serious problems running Davinci in CUDA mode on my Hackintosh with 1080Ti - I can't export anything except 1080p footage/timelines without crashes and reboots.
All UHD and higher resolution exports in CUDA mode continuously crashing my Hack...
The problem exists both in DR 14-15 and in Premiere too.
In Metal mode render goes slower, but stable.
Using Neat Video on 5-6K and higher res RED crashing my system even in Metal mode.

Grading in Metal mode is uncomfortable because of serious lag between changes made on panel or with mouse and interface/grading monitor response.

I'm using OSX 10.13.3 because it's much more stable than 10.13.4 on my system and there are no any reboots outside of Davinci/Premiere.

Today new 396.64 CUDA driver was released, I'll test how it works tomorrow.

Have you experimented with changing available PCIe slots for that svelte 1080ti you've got there?

Kindly let us know which slot number you've currently got it in, and which number you moved it to if that does the trick for you.

Cheers.

Now that I finally updated to High Sierra (yes, I'm very hesitant about such things) and I'm running 15b3, I can report a slight advantage of Metal over OpenCL. Depending on the features in use, it can be up to about 10% with my Radeon Pro 580 8192 MB, but normally its less than that.
Obviously y can't comment about CUDA.

answering to this old post hopefully you figure out your crashing but if it is still crashing post your EFI folder I had the same issue once I removed few kexts the system is stable with CUDA
