Can DAZStudio use more than 1 video card

I have 1 nvidia1070 card if I install another, same or better(if possible to do different card) video card would this decrease render time or just wishful thinking?

    I use a 1080 and a 2080 and combining them does seem to help. I run all my video inputs through my 1080 and just let the 2080 be a dedicated render machine though.

    Yes, as long as they are both nvidia cards.  Just check that your Power Supply Unit can supply enough power for both of the cards.  The cards can be different and you do not need any kind of link between them.

    I've done this a couple of times as I upgrade the main graphics card, and you may have to reinstall the drivers.

    Once thing to be aware of, if the cards do not have the same amount of video ram then on larger scenes the smaller card may drop out, but the card with the larger memory will keep going.  After installation, it is best to test out a simple scene such as a few primatives with shaders to check that everything is working.

    This is the gateway drug.. if some is good, more is better.. so yes.. you can use as many* as you can cram in your PC.

    As long as you don't need to cool down your home in the winter due to all the heat produced by your DS rig, the habit is still under control

    At one point, I had 3 x GTX970's and 2 x RTX2080 TI's all connected to my gaming/rendering rig.  Had to get 3 PCI risers and a second power supply to power the 2 2080TI's that were mounted externally.  Got some insane rendering times in the benchmarking thread.  Had to turn off the room heater.  Just sticking with the 2 2080TI's now.  Waiting for RTX 3080's to get into stock because my case has a vertical PCI mount.

    If you got a 2nd 1070, it should cut your rendering time down by 1/2  if you ran the benchmark test, 1/3 if you had 3 1070's.  So the improvement is pretty much linear.

    If you got an RTX 3070, the performance improvement will be insane.

    ...hmm that's 13,696 + CUDA 156 RTX and 1,088 Tensor compute cores.  Yeah I'm surprised that didn't come close to creating a singularity.

    As I understand it, if you have more than one card, the VRAM isn´t cumulative. Two 8GB cards will not give you 16GB, it will still be 8GB, just faster.

    Thank you for all the inputs. Now is convincing husband to get another video card laugh

    That's right.
