Yup, ray-tracing is slow in AE -- no doubt about it. But can we say anything else? Not without some extra information from YOU:
And when thy ask for version numbers, the're asking for them right down to the very last decimal point. It makes a difference. So does telling us the obvious stuff like Mac/Win, graphics card maker & model number, etc.
Well, simple: If it's slow, it's rendering CPU only and perfectly normal, given that AE's Raytrace 3D must be one of the worst raytracing engines on the planet. Nothing will change that if your GPU is not recognized/ supported.
After Effects CS6 188.8.131.528
Windows 7 Professional 64 bit with Intel Xeon CPU 11GB RAM
NVIDIA Quadro 600 Driver with CUDA
The problem happens when I’m trying to render a raytraced 3D project preview as well as the final output that could take an hour for a 30 second project. I used to be able to see the OpenGL info (NVIDIA driver) but nothing in the CUDA section and I couldn't choose GPU. So I updated the NVIDIA driver today, installed the CUDA driver, and now nothing appears. I included additional screenshots if that's helpful. Thanks!
Update! updates for Adobe Media Encoder, Premiere Pro, After Effects, Prelude, Audition, and SpeedGrade You're missing some very important bug fixes for AE. CS6 should be version 11.0.4, not 11.0.0.x
This page lists all the GPUs that are certified to work with the ray-traced renderer in AE: System requirements | After Effects There are a number of webpages out there that walk you through a "hack" that helps AE use NVIDIA GPU's that aren't on this list to make them accelerate the ray-traced renderer. You could consider going that route. It's technically unsupported by Adobe, but it's unlikely to cause any harm to try it. Just make sure you make a backup copy of any files you're changing.
Alternatively, you could consider upgrading to version 12 or 13 of After Effects which both come with Cinema 4d for free! details of CINEMA 4D integration with After Effects
Adding more RAM wouldn't hurt either (it wouldn't help for this current problem, but 12 GB is on the low end for AE work in general).
