List of Compatible Video Cards for Daz Studio 4.9 and beyond.

Is there is a list of videos cards that are not compatible with Daz Studio 4.9 and up? If so, is it on this forum?

I am planning on building a new setup and this information would be of great help.

I usually go with Nvidia videocards and Windows so this new setup will be no different unless Ryzen and or other videocards are far better than Nvidia.

I would appreciate the input.  Thanks! :)

    If you plan on rendering with Iray you are limited to Nvidia; Iray is an Nvidia product and does not support AMD cards.

    You want as much video memory as you can get/afford - if the scene does not completely load into the card vram the card will not be used in the render; under Iray, cards are fully independent. A 4 GB and 6 GB card does not give you 10 GB; they give you two cards that can simultaneously process the scene IF the scen fits in less than 4 GB. If the scene is larger than 4 GB only the 6 GB card participates, and if the scene is larger than 6 GB then you'll be rendering with just the cpu.

    Adding to the fun, there is no precise method of determining how much vram a scene will need until you try to render it.

    ...there actually is. Open Task Manger.  The start Daz.  Not memory usage for the Daz Programme in the Processes tab.  Next load a scene Note the memory usage for the Daz Programme with the scene open.  Subtract the first value form the second.  That will give you a reasonable approximation of the scene size in system memory.  the file size in the scene folder are the compressed file.  It's not absolutely precise but does give you a pretty decent ballpark value to work with.

    A few more points that may help:

    For Iray rendering, the more CUDA cores the faster the scene will render.

    If you buy a Pascal (10**) series card you will need an up to date Nvidia driver.

    Make sure your PSU can handle the power requirements of the GPU.  Larger GPUs will require 180 to 250 watts. Also, cheap and cheerful PSUs are a mistake, if they fail they may take your entire system with them.

    Cheers,

    Alex.

    Hm, ok - but is it possible to configure DS to properly use virtual RAM in case neither card- nor physical RAM do suffice? Sometimes I could use that... (especially since I anyway don't have a working GPU atm.)

    I really appreciate all the information provided, thank you. :)

    That happens automatically. However your render time will probably go from minutes or hours to days.

    ...with only 10.2 GB of available memory (according to the Daz programme log file) I often have Iray render jobs dump to virtual memory. I really wish we could get batch rendering because then I could close the scene and Daz programme down to conserve system resources.
