MaxtoA GPU

Hello i just wanted to ask, when Arnold renderer is approximatly able to render fully functional with the GPU?

Also when is it possible to render with CPU and GPU simultaneously, if that is planned?

Been using Arnold GPU and you can see the improvements on each release. You can switch from CPU to GPU almost without any issues. In terms of GPU I see it as a good tool for lookdev. Also keep in mind that other GPU renderers also need specific workflows to be used properly and there is a limit to what you can do.

I plan to invest in hardware to speed up rendering by using Arnold, but cant decide to add another GPU or replace my CPU from Intel to AMD without knowing when the GPU is usable like CPU.

Btw. what is the workflow for GPU Arnold?

I was also in your situation. I was always an AMD guy, but because of GPU I went to Nvidia. My workflow so far with Arnold GPU is for lookdev. Check the list of things that aren't supported, I believe is only around 5% and will not stop you from working.


For Arnold GPU, keep an eye on the Render Message window. It will tell you if something is wrong. For any kind GPU renderer you need to play safe. Try to go easy on textures size, check the geometry to see if isn't too heavy. Remember that if you have a GPU with 11GB, your scene if is bigger will not render.

At the moment I am on the Beta, and some bits were implemented to help when using 4k or even bigger textures. On every release, there are meaningful updates and improvements.

There's no exact when. Each Arnold update we add more features and improvements to Arnold GPU. It's an on-going process.

Thx for the answer, that was all i asked for.

But can you tell me, if its planned to implement rendering with CPU and GPU simultaneousy?

A list of supported features and known limitations can be found here. Please let us know if there is any particular problem that you are having with GPU.

That wasnt my question. I wanted to know, when you can use the GPU without limitations and if it be possible to use both CPU and GPU simultaneously to render...

The thing is, i plan to invest in hardware to speed up rendering by using Arnold, but cant decide to add another GPU or replace my CPU from Intel to AMD...

And to be honest i´d like to stay with powerful single thread CPU for the simulation engines and render with the GPU.

Which limitations? Please be specific.

You just pointed with a link to the limitations in your first answer...
Im sorry, but i dont understand how my question is not clear enough.

Right now im rendering with my CPU, but would like to use my GPU instead, which is more powerful and should speed things up. But i cant, because of the limitations. Its not fully functional like CPU and throws errors when used with my OSL maps.
Furthermore its noisier with same CPU settings, so you´ll need to increase them, which ends up in more render time, which makes rendering with GPU absolutly not an option.
