I just bought a brand-new Macbook Pro that has an AMD Radeon R9 M370X 2048 MB graphics card. It's plenty powerful, and it was basically the only option because it seems that Apple has turned away from the NVIDIA cards in their latest lineup in favor of the AMD Radeon. But in After Effects, I get the message, "Ray-tracing on the GPU requires an approved NVIDIA graphics card and CUDA 5.0 or later." I'm interested in speeding up the rendering process and the whole idea of getting a new machine was to make sure that everything works perfectly and all features are available. So what are Mac users to do if you can't get an NVIDIA graphics card in their new machines? Not do GPU ray-tracing? Switch to PC? Wait for Adobe to update this feature to work with the card? Is there a patch? I have 14 days to decide whether to ditch this machine. Thanks!
The error message that you're seeing only refers to the ray-traced renderer. The ray-traced renderer is considered obsolete. If I were you, I would tick the box to never show that error message again and never worry about it at all. (In fact, that's exactly what I did on my MacBook Pro.) The ray-traced renderer was just a clunky way to create 3d geometry natively inside AE. It relied on NVIDIA's Optix library and it didn't make anything faster. In fact, it made everything slower. Since we have a much more powerful way to do 3d in AE, you can happily ignore the ray-traced renderer. (Some great training for Cineware here.)
