I wanted to know if my MacBook pro is compatible to use an after effects template that I got off the internet.
It is a MacBook Pro, retina, 13-inch, early 2015, with the OS X Yosemite 10.10.5
Processor: 2.7 GHz intel core i5
Memory 8GB 1867 MHz DDR3
Graphics: Intel Iris Graphics 6100 1536 MB.
Please tell me what I'm supposed to do. I'm pretty clueless.
Ray-traced rendering without a compatible NVIDIA CUDA card is going to be very slow to render and painful to work with. Your machine will do it, but it will be slow. You can ignore the warning about the GPU and do not under any circumstances try and install a CUDA driver.
Ray-traced rendering is no longer being developed because NVIDIA changed course and headed in a totally new direction. The folks at Adobe are now concentrating on integrating 3D elements into AE with the Cineware plug-in and C4D Lite that is included with all recent versions of AE. It is far more capable than Ray-traced rendering was or ever would be.
