Was trying to solve another problem by updating drivers and installed the studio drive 566 and daz (and the computer) would still see the 1080 ti but not the titanX
So switched to the game driver 566 and bingo I have two video cards again.
Which is interesting because you need the studio driver and a quadro card to use the cards like the K-80 etc.
This is just as in info post. Unless, there is a work around to make the studio driver see multiple cards because theoretically it should work better for daz?

Are you sure the TitanX iss till supported by the latest drivers? The Studio drivers are the same as the game drivers, just slightly older (usually) versions that have had more testing and were not given newer, riskier code to manage the latest games.
same numbers and only way to tell them apart is one has nsd in the download name.
But it uses both cards as verified by watching with GPU-Z during the render.
The render was just done with the 566 game driver, it's the 566 studio driver that didn't see them both. (When the system was running, so not in daz either).
If you're running an original Titan X, it's maxwell generation, and that generation has never had 'studio'(NSD), only game ready ones.
As a suggestion, when searching for drivers in a multi-gpu system, you'll generally want to use the oldest card for the driver selection.
In your particular case, search drivers for the Titan x, not your 1080 ti.
Even then, double check the "Listdevices.txt" file in the executable to make sure it's compatible with both cards.
The exception to this, is when you have a quadro or tesla, and any consumer class gpu(GTX, Geforce RTX, etc.) in the same system.
Unfortunately, tesla and quadro drivers don't, according to the listdevices.txt file, support consumer gpus, so you'll need to use either the Studio or game ready drivers, depending on combination.
With a quadro and consumer card, you can use either the game ready or studio drivers, as they are generally supported in both.
With a tesla, you'll need the Studio drivers, as the game ready lack support.
If you are running a quadro and a tesla, on the other hand, you should be using either the Production Branch Driver or the new feature branch, as they're slightly different from the consumer studio drivers. Mostly it's just the 'fluff' that doesn't work with these cards.
Lastly, NSD stands for "Nvidia Studio Driver", so if a driver file has that in its name, it's a 'studio' driver, if not, it's game ready.
Tesla and quadro driver's contain no such designation, and there's no differentation between Production and nee feature, in the file name.
Peace folks.
Right ~ there're two "Titan X" models, GeForce Titan X (Maxwell as DrunkMonkey mentioned...) and Titan X Pascal... Studio Driver (since GeForce 10 series..) only supports the latter one, while Game Ready Driver supports both.
So, in some cases, like yours, using Game Ready driver will just do.
Quote from Nvidia Dev: "All NVIDIA drivers provide full features and application support for top games and creative applications.... If you are both a gamer and creator, choose Game Ready Drivers. "

( I'm both a gamer and content creator but I do it on the contrary, I only use Studio Driver... so far so good, surely depending on the games I play )
The card does say geforce GTX as well as TitanX.
But at this point some how the iray engine in the program does split the load.
The titan is 12g and 1080 only 11g and it wasn't until I switched to the win10 machine with just the 1080 in it that I realized how many of the scenes I had need the extra 1g.

OTOH I got tired of waiting for the long renders of my large scene so started rendering them from fore to background and then stacking them in PS with greatly reduced render times for the parts and of course the ability to edit and change sections.
I think each one of these has at least five different parts.
And look there I've updated the train but only have to redo the train section of the second picture to update it.
