SVRT doesn't use hardware at all but it's only available when minimal changes are made to your source clips. If you've used LUTs those will have to be handled by the CPU regardless of what GPUs are attached.

As far as getting PD to utilize a specific card, your best bet is to read this post and see which two cards Windows decides is "power saving" and which is "high performance." You should then be able to select the one you'd like for PD to use.

That applies only to laptops (and Surface tablet). He has two discrete GPUs.

Maybe this way - in nvidia control panel there are several Cyberlink software - assign all of them to the faster GPU. It won't matter too much, but at least he can experiment:

Wow, all the years I've used nVidia and I had no idea of the per application controls. I've already adjusted some for specific applications and am now seeing the expected behavior per gpu for those.

With PD, I've specified each GPU, ran the PD optimizer, yet the slower GPU is the only one that continues to be used. It doesn't appear that these setting have much, if any, impact.

PD doesn't use CUDA or 3D, so I'm afraid those settings won't make any difference.

Was sonic67 correct that the Graphics Settings option I suggested doesn't work with discrete GPU cards? I've never had more than one external card but I assumed you would still have that option available. If it's only tied to which GPU is driving that specific monitor, then I can see why it wouldn't work here.

However, that may be your answer. Are you driving a monitor from the higher-performance GPU? Launch PD and place it on that monitor then close it. See if it comes back up on that monitor after relaunching it, then see if PD will use the GPU it's actually running on.

Sadly nvidia control panel doesn't let us choose the card that does the video encoding (NVENC), only the 3D CUDA cores.
In my rig, the weaker Quadro P620 NVENC is used instead of the GTX1080 one. That's valid when when recording games.
Thhose are the same generation, but P620 has just one NVENC chip, while GTX1080 has two:
