Noise / grain on octane live viewer, no happen before.

[Cristal]

Hi,
I have a huge problem that I can't solve. A week ago everything looks perfect, octane and cinema 4d all good.
A week after I open cinema 4d and look at the octane live viewer and is all noise, It was like if I downgraded my gpu or something,

The thing is that a week before it was all much faster and without that noise. This render, for example, is not a complicated one, and takes so long to see it.

I'm totally desperate. And I try:
- to change octane render version several times
- I was working with c4d 20, and I try the trial of c4d 23
- I restored Windows 10!. I deleted all programmes to see if it was fixed
But nothing seems to work. And octane seems to slow down even c4d work.

Oh!, And I have an AMD Ryzen 9 3900x 12 core / 32 MB RAM / Nvidia Geforce RTX 2070 SUPER

Please please help!

wait until maxsamples are calculated and try to change environment setup if it's still noisy.

Hi aoktar,
I wait, but that is not the thing. I know that final render will be ok, I can use denoise and all fine, but What I say is that now is too slow, and I've never seen before that kind of noise. A week after it all works fine. I try with my laptot and it happens the same thing...

Hi,
please check to have set the MoGraph cloner to Render Instance.
Now your scene has more than 32 Millions polygons!

It is not the scene... look here. Just a sphere, background plane and hdri light.

Besides last render files works great a week ago... I'm lost...

Weird, we don’t have other similar reports, as far as I know

What about the installed Nvidia driver?

Please, download and run GPU-Z:

And share a screenshot from the Graphics Card tab, for all the available Nvidia GPUs, thanks:


Please, also download and run octanebench 2020.1.5, and share a complete screenshot of the result, thanks:

Ok, nice that you have also contacted the Otoy Support, so I can follow you via Support ticket, and investigate more deeply.
See you on the ticket.

Silly question but you know that little rectangles at the bottom of the live viewer saying "Main" and "DeMain" are actually buttons that swap between denoised and not-denoised right?
