Hi Mike, re: limiting threads - I guess it might be possible that the nVidia driver is trying to use some type of threading itself and that may be competing for cpu resources as well.

Can you look in your nVidia driver settings and see if there is a checkbox there named anything like "Threaded optimization" and what happens if you turn that off?

I think that probably MoI is able to use the cores more efficiently for its particular workload than what the driver was trying to do on the driver side alone.
