Ray-tracing GPU greyed out in After Effects
Hello all,
I am not a computer whiz, so my technical vocabulary is limited, but I need help. Adobe After Effects kept crashing over the simplest tasks like moving an object. After some research I found that it might help if I were to switch the ‘Ray-tracing’ tab under After Effects> Preferences> Previews> GPU Information from CPU to GPU. However, the GPU option is greyed out, with an excerpt saying ‘(GPU not available – incompatible device or CUDA driver). I downloaded the newest NVIDIA CUDA driver, and it’s still greyed out. I tried the GPUSniffer in the terminal and it says ‘Did not find any devices that support GPU computation.’
Under ‘OpenGL’ in After Effects GPU information it says,
Vendor: Intel Inc.
Device: Intel HD Graphics 4000 OpenGL Engine
Version: 2.1 INTEL-8.16.74
Total Memory: 1.38 GB
I’m working with CS6 on a Mac Mini.Any ideas? Help!
Thanks

Mac Mini with its onboard Intel graphics is not compatible with GPU acceleration in AE, regretfully, and there isn’t much that can be done about it w/o changing the computer.

You must uninstall that.
If you don’t have Nvidia CUDA hardware (which you don’t), you must not install Nvidia CUDA driver software. If you install a driver for a piece of hardware that you don’t have, you can badly confuse applications (like After Effects) into thinking that your computer has capabilities that it doesn’t. In this case, you can trigger a crash, since After Effects may try to call hardware that isn’t there.

That’s not entirely true. It’s only true about the GPU acceleration of the ray-traced 3D renderer, which depends on CUDA.
The OpenGL features work fine on the Intel GPUs.

[Todd Kopriva] “The OpenGL features work fine on the Intel GPUs.”
Got it, thanks Todd.
