Hi Dionysios,

Could you try and roll back to a previous driver version and see if that helps?

Cheers,

Rowan

Yes, I found the problem!

The issue is produced with the latest Nvidia Driver 471.11.
Resolved if I install the previous one 466.77, so it is the Nvidia latest driver responsible for the artifacts!

Thanks!

And for your info I confirm, my second workstation who uses a 1080 with those latest drivers, doesn't produce this problem, the 3080 RTX yes.

So issue resolved if the Nvidia Driver 471.11 IS NOT installed on the system.

Hi all.

Just a reminder, is Nvidia aware of the Denoiser issues with it's new driver releases?
For now only the 466.77 works as it should.

HI, just an update...

Installed last Nvidia drivers + last daily build and the bug is still here.
Probably they didn't work on it yet.

Thanks,

A small update!

The new daily build seems to work at the end.
If I open an old CXR file, the problem persist. If I render a new one (latest September 6 2021 build), it seems ok.

I guess the old CXR files contain the bug denoise information inside, right?

Thanks again,

Hi,

I'm glad this is working for you now. I think you are correct that the file has the old denoiser info in it.

Please let me know if this issue pops up again :)

Thanks,

Rowan

Bad news, the bug is still here at the end but is more random than before.

I've rendered an image 8.192x8.192 and at the start of the rendering the denoiser worked fine. Once the rendering finished the bug was present all time.
So, Nvidia unfortunately didn't fix the problem and is still here.

Btw, do we have other users with the same problem? I've noticed that it happens only with the new RTX cards.

Thanks and have a nice Sunday tomorrow.

Hi,

I have contacted nvidia again to see if they made any progress on this.

I'll let you know when I get some more information.

EDIT: I have some more information, the nvidia team informed me that they have fixed this issue and it should be included in the next driver release which should hopefully be quite soon.

Cheers.

Rowan

Hey Dionysios,

This is fixed now. I just tried with the latest driver 472.12 released on 20/09/2021.

I tried with your cxr which previously was failing and it now denoises correctly.

Let me know how you get on.
