DAZ Studio Test Scene – share your Iray Render Speeds

- by

I’d love to see a decent Iray render speed comparison between the current NVIDIA graphics Cards, specifically for DAZ Studio performance. All we need is some data from a static test scene, render it on a variety of systems and compare the results.

Well here’s such a scene! Please download it and render it on your system, then leave a comment below with your GPU configuration and how long it took for the scene to finish.

To take a time reading, head over to Help – Troubleshooting – View Log File. Scroll to the end of that file and you’ll see a line that reads something like this:

Total Rendering Time: 17 minutes 20.70 seconds

To submit your results, I’ve made this handy Google Form (now closed) that will add your entries to a big spreadsheet. You can use it multiple times too, which will come in handy if you have more than one GPU. You can submit a result for each single GPU and for all GPUs combined. You can even add one pass with your CPU enabled, and if you’re game, try with OptiX on and off. You’ll be surprised about the differences it can make.

You’re more than welcome to elaborate on your results in the comments below. I’ve migrated all submissions into the sheet for easy evaluation, and I’ll compile a list of the results with a snazzy graph in an upcoming post.

Update 2023

Thank you for your participation in this project that started in 2019! Since then we’ve had various updates to both Daz Studio and the Iray render engine under the hood, and have closed the submission form. I have collated most of the submitted results, and you can read up on them in this article.

    • Thank you so much, this was very thorough! I’m off this whole week, so I’m hoping to compile all these results into a handy reference table in the next couple of days.

  5. Hey – first thanks for your nice vids.
    So here are my results in case you are still collecting :-).

    Ryzen 9 3900x (12x Core)
    32GB RAM
    2080TI OC (@rendering not in overclocking mode)

    Optix = off
    Total Rendering Time: 4 minutes 59.33 seconds

    Optix = on
    Total Rendering Time: 5 minutes 1.14 seconds

    • I do indeed, thank you so much for submitting them! I’d like to start again soon with a new set and see if DAZ Studio 12 makes a difference for render times. Usually “newer” means “faster”, but sometimes that’s just not the case. Which version did you render with?

      • Hey, I got a Total Rendering Time of 4 minutes 32.31 seconds with
        AMD Ryzen 5 2600
        16 GB Ram
        2x RTX 2060 Super
        OptiX: off
        (only GPU rendering)
        I got DAZ Studio and NVIDIA 422.19 Studio driver

        With OptiX on I got a Total Rendering Time of 4 minutes 40.29 seconds

        The RTX cards seem to be better with OptiX switched off, where the “old” GTX cards seem to be better with it switched on.

        • Hi Otto, thanks for doing the test! OptiX can vary a lot, like on my RTX 2080 OptiX enables renders faster than with it disabled. On my GTX 970 it renders faster with it enabled.

          NVIDIA actually made a change to the OptiX API, so the latest version of Iray no longer exposes that option. Hence, in the current Beta of DAZ Studio ( that tick box is gone. I guess from now on Iray uses it under the hood when it speeds up the render.
