Does CUDA accelerated A/V processing actually work

[nsd3]

I've tried DVD FAB ripper on two PCs I own, both with different Nvidia graphics cards. All drivers are up to date, and within DVDfab settings, the cards are detected and the CODECs are enabled accordingly. When I rip a blue-ray disc. I never seen any sign (on either PC) making use of the CUDA processing. My GPU(s) never move above 2%, no matter what or how I measure them.

The cards are a GTX780 and GTX970. So does anyone actually have DVDfab and any Nvidia card working for them? I'm just curious!

I have the GTX 1060 and GTX1660 and they both are working fine with CUDA. The Nvidia Graph goes up-to full (50x).

I think the minimum card may be a GTX 1050 unless you are using a motherboard with on-board GPU.
