Daz refusing to render on GPU on new 5090 laptop

AndrewJJP

I have a new laptop, and I'm setting up Daz on it. The card is a mobile 5090, and the scene has a cube in it, and nothing else. I'm running the latest Studio driver (591.44, 4th December).

In "Render settings -> Hardware", I see the CPU and GPU, as expected, and the "Help -> Troubleshooting -> About your video card" looks sensible.

If I leave the CPU as an option, the log says this.

Rendering with 1 device(s):
    CPU

If I disable the CPU, it says this.

Iray [ERROR] - Cannot render: found no usable devices.
Please update your NVIDIA driver ... or enable CPU rendering.

I do some video editing from time to time, and my video editor uses the GPU with no problems. The GPU is working.

I know how to use Daz, but setting it up is not something I do much. I have tried reinstalling (although my expectations were low - it doesn't feel like an install problem). So does anyone have any suggestions?

Thanks :)

I am trying very, very hard to stay calm. I'm reading now that Daz does not support 50x0 cards. This machine cost a fortune.

I will not shoot the messenger if this is the case, but isn't that quite a critical problem for Daz? Is not not their top priority? Soon, you won't be able to get anything less than 50x0.

Maybe I'm wrong, and in the past year, Daz has actually fixed it, or will fix it soon, otherwise this is a brick. Please, please, please can somebody help me out? Pretty please?

You have to render with DS 2025 Alpha that is the only version supporting Nvidia 50 series cards.

The fix is to use daz Studio 2025 for rendering (you can set the scenes  up in DS 4.24). Because of chnages nVidia made to the way Iray itself is compiled it will not be possible to get 50x0 support in DS 4 (there was a version which would have worked - except it had unacceptable bugs).

Right, the answer seems to be use the alpha. And that does render on the GPU, but I guess it also increases the TK version and will break all the scripts.

So obvious questions:

 - I'd be reluctant to use a beta, let alone an alpha, but I don't have a choice. Is it feasible to use it as a serious creative tool?

 - Will I be able to open the scenes i create on my desktop machine, which is running 4.24, but works.

And for expectations, are there even vague timelines for Blackwell support in a released product? My feeling is that if after almost a year, we're still at the alpha stage, this isn't close, but also that this will become so critical that it will take Daz out of the market within a year or two. So I am guessing they are trying, and I know they didn't cause this.

Thanks Richard, I think we crossed over. It was a bit of a shock, not something I ever imagined. And it's very clear to me that it's undesiarable for Daz, they aren't "being lazy". I will see how it goes.

Thank you too :)

An alternative is to learn how to get your scene into Blender. Not only does it render like a champ on virtually all GPUs currently in use, but if you invest the time, you'll end up with a much more powerful environment.

These days, porting your paid for DAZ assets to Blender is just not that hard anymore. And once you get your head around material nodes and then geometry nodes, you may never look back.
