Regarding the Arnold GPU rendering speed issue.

Please advise, I am rendering a clone scene using Arnold GPU and found that it takes time cost a lot, my graphics card is NVIDIA GeForce 3070.My scene is some clone diffuse material rectangle. My rendering time is very long and I am confused that CUDA is hardly working, is the rendering speed related to the number of faces? Previously such scenes and render sizes didn't take so long in Redshift, I'd like to know the cause of the slowdown that has helped me to optimise my rendering project, and the second question is whether there are any plans for Arnold GPUs to have a better support for NVIDIA DLSS3 and RTX, which will increase the rendering speed and save lives.

Is this happening with the latest Arnold plugin/Nvidia drivers? https://manage.autodesk.com/products/updates

Can you upload a log file?

I only have screenshot files, my NVIDIA/Arnold are up to date, and the final render time is 10 hours, which is a bit unbearable. Please help me.01.jpg02.jpg03.jpg

Do you have a scene file that we can test?

It rendered in 6 minutes for me. I used the OIDN denosier imager. Are you using the Noice denoiser for a reason?

I increased the sky samples to 3.

Do your ray depth settings need to be this high? That will also add to render times.

Btw, you might find it easier to adjust the light exposure rather than intensity in the future.

Thank you very much for your support, what graphics card do you have?
