Rendering problem with dForce

Hi, My Iray rendering ends in under a minute showing a blank screen when I render and image with a recent dForce hair product. It renders (but very slowly) when I select gpu and cpu but it won't render on just gpu which is my preference. 

 

When I delete the hair product then it renders fine so I know it's the issue. 

 

I don't really use dforce products so is there something I need to select?

 

Cheers

    You are running out of VRAM on your GPU, what are your system specs (CPU/RAM/GPU/OS)?
    Which version of DS and which version of Nvidia drivers (xxx.xx)?

    dForce hair can use a lot of resources so it's possible it doesn't fit in your card's VRAM.

    Hi thanks, i'm using nvidia 1660 16g of ram. I think you're right it cant handle it. I guess I'll have to wait hours instead of minutes unless you know a better way?

    On a 6G GTX card (GTX 1660), the limits to what can be rendered can be exceeded with just one "wrong" asset.

    On my 8GB RTX card running on W7 Ultimate, I can render a scene where Geometry+Textures+Working Space take 5.7GiB's of VRAM (as reported by DS Log)
    With you having just 6GB's, the amount would be reduced to 3.7GiB's, the Working Space should have about 1 GiB, which leaves 2.7GiB's for the Geometry+Textures, but...

    You are running a GTX card that needs some additional VRAM for emulating the RTX functions in software and W10 eats more VRAM to start with than W7, how much VRAM is used for emulating the RTX functions and how much more W10 reserves, I don't know since nobody has taken the time to figure them out and release the information in here and I have neither to test.

    As others said: your GTX 1660 does have 6 GB not 16 GB. That is not much for DAZ Studio.

    What you can check - assuming you are using Studio 16:

    Open the log file and search for information about vram.
