I created a simple scene in After Effects that's using the raytracer engine... I also have GPU enabled in the raytracer settings for After Effects.
When I render the scene in After Effects using the built-in Render Queue, it only takes 10 minutes to render the scene.
But when I export the scene to Adobe Media Encoder, it indicates it will take 13 hours to render the same scene.
So clearly After Effects is using GPU accelleration but for some reason Media Encoder is not.
I should also point out that my GeForce GTX 660 Ti card isn't officially supported and I had to manually add it into the list of supported cards in:
C:\Program Files\Adobe\Adobe After Effects CC\Support Files\raytracer_supported_cards.txt
C:\Program Files\Adobe\Adobe Media Encoder CC\cuda_supported_cards.txt
While it's not officially supported, it's weird that After Effects has no problem with it yet Adobe Media Encoder does...
I also updated After Effects to 12.1 and AME to 7.1 as well as set AME settings to use CUDA but it didn't make a difference.
Any ideas?
