CUDA is a technology that is only available on Nvidia graphics cards.
Hi Ray, thank you for your comment. My question is if amd wx7100 should work seamlessly with After Effects or if there are is need to install some driver for the Card to work well. The 2 GB Nvidia Gtx 750 that i replaced was performing better that the current 8GB amd wx7100. Clearly, there is something wrong...
It depends on your version of After Effects. If it only supports CUDA, then you will not see the performance gains that would be obvious if it was using the open standard OpenCL.
