LAV Video Decoder + MadVR

Hello,

Could you please help me resolve following problem.

I recently bought a new laptop with UHD and GTX1080.

I setup MadVR for the first time + I changed some settings in LAV Video Decoder (picture attached)

So now when "Hardware Devide to Use" is in Automatic mode it choose Intel GPU and picture quality is stunning but when I put it in full screen mode it is laggingas it has no enough power.

When I change it manually to Nvidia quality really drop but of course there is no lagging.

What can be set-up wrong here? What can I do to enable Nvidia in Automatic mode?

You can set the Nvidia GPU as preferred with Nvidia Profile Inspector:
