Question / Help Select what GPU should NVENC use?

[charlie20083]

...As title
and sorry for my bad English :-(

My computer has 2 graphic card
one is MSI GeForce GTX 670, the other is Dell GTX 645 (OEM)
and both of them support NVENC.

and I can use NVENC in Win 10 without any problem.
but it use GTX 670 instead of GTX 645 which is usually idle...

only one way to use GTX 645 is
"Connect the moniter to GTX 645, disable GTX 670 in Device Manager"
and all 3D and NVENC will use GTX 645 to process

if "Connect monitor to GTX 645, and let GTX 670 enable in Device Manager"
then the 3D will process on GTX 645, but NVENC will process on GTX 670
because the Video Engine on GTX 670 will have some load?

so, my question is
"How to define what GPU to calculate NVENC?"

Folding Home and define what GPU it should use
no matter on GTX 670 or GTX 645 or Both?
so will NVENC in OBS is possible to do it or not?
or NVENC isn't based on CUDA so I can't do that?

Currently, you can't select which GPU to use for NVENC.
