At the start up of after effects cc, it says i need to download a NVIDIA graphics card for ray tracing to enable CUDA. But i have an AMD graphics card and it wont allow me to enable CUDA. I've tried using Element 3d on After Effects and i cannot because of this issue.
Do not under any circumstances install the CUDA driver. You can ignore the warning and your system should work just fine. Ray-traced acceleration is a very minor part of AE that you shouldn't worry about. If you're still having problems then something else is wrong. It is not the driver or lack of one.
