I am using After Effect CC 2017 and I cannot activate GPU ray-tracing on my MacBook Pro. I have a NVIDIA GeForce GT 750M 2048 MB graphics card with a built in Intel Iris Pro 1536 MB. I recently installed the most recent CUDA driver (version 8.0.53) and I don't see after effects even recognizing the software. Here is what the dialogue box looks like:
I am also unsure of what it means to not have enough memory for my GPU. I have no other programs and it will still say that.
It means what it says - your card is unsupported and you can't do anything about it.

but you should not worry about it, Ray tracing is dead, and CC2017 has the Cinema4D Renderer that does almost the same thing and works on the CPU not GPU.
Let us know if that advice helps you with restoring ray traced 3D composition capability.
