No CUDA in After Effects
Hi all
My question is with regard to cuda in after effects. I have a 12 core mac pro with a gtx 980 in it. Although in premiere I have to option to choose the Mercury Cuda acceleration, in After Effects I only have the option for the opencl one. Could somebody enlighten me why? I do know that AE does not use the gpu for accelerating (with the exception of ray tracer) but I am curious as to why there is the option for opencl and not cuda.
Thanks for your time.
VSpecs: OS 10.11.6, Latest Nvidia web and cuda drivers.

The latest release of After Effects (CC 2015.3) adds some support for GPU acceleration. It’s only 3 effects: Gaussian Blur, Lumetri Color, and Sharpen. On Windows, CUDA and OpenCL are supported. On macOS, OpenCL and Metal are supported. CUDA is not supported on macOS.

Thanks guys for your replies! Thanks! I was curious as to why I only have opencl whereas in premiere I have the option for cuda as well. I thought for a moment that there was something wrong with my setup!
Btw, metal is also not available in CC 2015.3 as it causes panics. According to Adobe they are investigating this issue, which will be addressed in a future update…

It’s no big loss. OpenCL works way better than Metal for these effects at the moment.

Cheers! I would expect AE to utilise hardware acceleration more extensively, being a compositing app. Then again, what do I know 🙂

Ae’s original codebase is 23 years old; that’s why the architectural changes they’ve been making in CC 2015 are such a big deal. There’s a lot of stuff in Ae that’s been updated over the years, but not re-thought. Until now.

Out of curiosity, I ran the ALU 2 test in both GFXBench GL and GFXbench Metal. GL yielded 60+ fps whereas metal, 120+. Then again, apple is quite behind with its implementation of opengl.

Out of curiosity, are you happy with your GTX 980 card? I have a mid 2012 Map pro5,1 and was looking into purchasing this for GFX and editing in AE and premiere. Have seen a lot of reviews on this card and the GTX 980 ti for gaming, but not much on using this with adobe products.
