Choosing which GPU is used by Mercury Engine
Currently Mercury Engine automatically use GPU that is used for display (one that is connected to a monitor). I wish it would be possible to accelerate effects with other GPU, not one that is used for displaying things on the monitor.
IMHO it would save some VRAM for OpenCL/Metal purposes, since second GPU would not have to store video buffer.

I agree. Needs a GPU selection option. In my case, it defaults to slot 1 GPU, but that is not my main display GPU, or may not be the one actually available at the moment of AME render.
