Give option to explicitly choose a GPU for rendering.
Have an option in preferences where you can explicitly choose which GPU to use for rendering, much like the performance option in Lightroom.
Especially useful with mobile workstations.

Needs a GPU selection option. It defaults to slot 1 GPU, but in my case it's not the main display GPU or may not be the one actually available at the moment of AME render (busy with other render).
