Author Topic: Iray with GTX 10xx  (Read 27318 times)

Hello,

NVIDIA is currently working on adding support for these new GPUs, but as for now Pascal GPUs (GTX 1080/1070) are not supported by the Iray rendering mode of Substance Painter and Substance Designer.

The currently estimated date of support is SIGGRAPH 2016.

So - to carry over the question at hand...

Okay - so I posted the question, on the Nvidia Iray forum, of how close are we to getting the driver support for Iray. Thread here: https://forum.nvidia-arc.com/showthread.php?14632-Will-the-Geforce-GTX-1080-be-supported&highlight=1080

Here is the response received:

It took us longer than expected. But Iray itself has the support.
    We need to release a version of the Iray SDK and then integrate it into the plugins.

    I totally understand that you are keen to use your newest hardware but I need to ask for your patience here. And for your understanding that even if we work for the same company we need time to adapt the software part to the new hardware and drivers. We want to deliver plugins that are well tested.

    Again, sorry for letting you wait
   


I'm confused - is this a driver we are waiting for (to use GPU Iray in SP) or will you need the SDK in order to configure Iray to work with the GTX10** cards??  ???

Thank you!

My thinking is the Iray people at Nvidia need to update Iray itself, using CUDA 8.  In that case, I suppose Allegorithmic will need to make new releases of Substance Designer and Painter with the new Iray bundled in it.  Or, if we're lucky, maybe there will be some easier way to update Iray (direct from Nvidia) on our machines that would fix both Designer and Painter without waiting for updates from Allegorithmic.

We possibly need new drivers, too.

I'm sort of guessing, trying to connect the dots.  If anyone can confirm or correct what I've said, I'd love to know what we should expect in terms of the process, regardless of the timeline.

Allegorithmic - would you please enlighten us on this topic? :)

I guess they don't know how it works either, Viking.  :o :-\

The estimated date of support was SIGGRAPH 2016.  It ended on the 28th.

I'm not mad that I don't have a functional copy installed on my computer yet today, but at least an update from Nvidia would be nice.

QUESTIONS:
a) Does Nvidia have a new ETA?
b) What will the process be like?  Does Allegorithmic need to do something, meaning after Nvidia is done it will take another two months before it works in Designer/Painter?  Or do we install a new Nvidia Iray dll, or just a new driver?

Hi,

We will need to integrate the new Iray SDK to support those cards, as mentioned in the NVidia forum. We should receive it "soon", although we don't have any official ETA yet.

Cheers,
Head of Product Management

Thanks for the info, Nicolas.

This isn't stopping me from getting work done, but I sure am looking forward to trying Iray on my new GTX 1080.  :)

Please update us when you have any news, such as timeline updates (even estimates).

A little bit of an update...

For Pascal GPU support - Please look for updates to your favorite Iray products starting in late September.
 Please realize that we require CUDA 8 for supporting Pascal, and that this is still in release candidate mode.

Yeah, I saw that. Not sure what that means in real time expectations, tho. Longer than I expected when I bought the hardware.

Don't understand this either...  :-\  They require Cuda 8?

Pretty lame!

I mean those cards are high end and I think some will use them for professional tasks, not only for gaming.
So why there is no iray support for this, is beyond me... it should be ready as soon as the card hit the markets.

but well - guess we have to wait another month  >:(

I am glad, that the allegorithmic guys are fast with updating thier stuff - I wish NVIDIA was also  :P

I wish nVidia and Allegorithmic could make a beta/experimental build for those of us who's got the balls to test it, using the experimental/early CUDA 8 versions. This update would be accessed through an alternative download, clearly stating it's a beta for Pascal support. Crossing fingers...

Octane have made a build using these experimental things.. And my GTX 1080 fuels Octane without a hitch.

Substance Painter is a great tool for making renders to TurboSquid, but now that I have a 1070 I'm limited to CPU and it takes forever... And waiting for a month at least for update... Not nice.  :-\

I had an Nvidia 560Ti, and was messing around in Blender, getting a feel for the whole 3D thing again (being out of it for almost 20 years now). The Cycles engine looked nice, but was kind slow on my GPU. I also discovered this new thing called physically based rendering rendering, maybe you guys have heard of it? ;) That lead me to Allegorithmic. I saw that my 560Ti wasn't supported, so I figured might as well upgrade my video card. The very next day the 1060 was announced, so I took that as a sign, and bought one.

Long story short: Cycles doesn't yet support CUDU compute capability 6.1 (it did work on the old card, just crashed every few hours). Now it seems I'm also waiting for an Iray update, and it doesn't look like it'll be available before my trial expires.

Oh well. I can put up with slow CPU rendering until then (the i7-4790K isn't slow, but I'm sure the 1060 will be much faster). At least the mesh painting part runs very well. That's life on the bleeding edge.
