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?
It is very hard to understand what you have written.
