That card was added to the list of those that can be used for GPU acceleration of the ray-traced 3D renderer in After Effects CC (12.1):
If you're using that version or later, and it's not working for you, then you need to give a lot more information, including exact version number of After Effects, operating system, CUDA driver, GPU driver...
OK I'll have a try, and I'm updating now.
Thanks a lot!
The problem has been solved thank you !
