Rendering with GPU

Hi. My processor i7-6700K (4 GHz) gets some high temperature while rendering reaching even 90 °C at times. Is it possible for GPU to help it? I have NVIDIA GeForce GTX 1060 6GB and Toon Boom Harmony Premium version 12.2.1 (11062). I go to edit->preferences->render and there’s this:
(see attachment)
There’s “enable graphic card acceleration” checked, yet i see on my GPU monitor that it’s not working while rendering. Can someone help me please?

I have some problem. GPU don’t work while rendering. Only CPU 100% loaded.
Does Harmony 17 can use GPU accelerator?
