The software is not using my graphics card at all, and there is no option to select it in the menus, or any advice in the manual. How can I get it to use it please?

At the moment it just uses the CPU for processing.

I have installed all the latest drivers, even Nvidia Studio, but it still doesn't seem to use it.

I am using Movie Studio 18 on a brand new Asus Rog Zephyrus Laptop with 32GB RAM, Ryzen 9, and Nvidia Geforce RTX 3060.
