on 2012 8 core mac i change graphic card nvidia 4000 for mac i enable cuda on prmiere pro but still render slow and i can't enable for after effect cc v12.1 can you help
I do not understand what you are saying. It sounds like you are saying that Premiere is rendering slowly and that you are unable to use the NVIDIA card you have to accelerate the 3d ray-traced effect in After Effects. Is that what you are saying?
You should offer a lot more information. I am not even sure which video card you have as your post is not clear. Is that a Quadro?
