about graphic card NVIDIA Quadro RTX4000 8 GB GDRR6 256 and After Effects

Hello, this web site mentions the benchmark testing of After Effects. It may help you to uderstand the capability of the graphic cards.

To underline @Myleniums statement, I've a GTX1080 and when rendering animations for 360 video, I see a GPU usage of 16% for a second.

I think you can use GPU acceleration on a RTX, but if you take in consideration working with such card, you expectations are going to disappointed anyways.

At this point support for the NVidia RTX architecture is utterly irrelevant. It simply doesn't exist in AE. Whether or not the OpenGL, OpenCL and CUDA features work on such a card is another question and entirely dependent on driver support. It's probably fair to say, though, that AE will ever only use a tiny fraction of your card's power, so it definitely seems overkill. That and of course changes in these modern cards' core architecture tend to be limited with legacy compatibly in the first place. In any case, you won't get a definite answer. As usual this is a case of "You won't know until you try."
