10.3 GPU Usage Way Up?

I haven’t been able to use 10.3 consistently but hadn’t checked GPU usage til now. Same project is def pulling more from the GPU BUT I arbitrarily turned off my Nektar T6, which is plugged into the USB port of my monitor and noticed a big drop in usage. not sure I can switch to a different USB port without spending the day moving equipment.

& I’m on a 2018 Mac Mini, 3.2 i7, 32G RAM.
