Denoise not working in 2021 working in 2020

[Dingbat]

i've tried this in MODO and Archicad, and also in standalone and it's all the same - Denoise works in 2020 but no 2021

latest drivers installed

you can see in the devices tab for 2021 the Denoiser memory is 0 bytes (denoiser is selected)

in 2020 the Denoiser memory is >500mb

none of the 2021 releases (RCs etc) have worked for me

Any ideas please?

Hi,

The denoiser memory data info in the device preference dialog is updated only after the first denoiser run (that is when the denoiser memory is allocated). So this window doesn't give us any clue.
Could you please render a scene with denoiser enabled in the standalone and then after it is finished(or the render might just be stuck at the end), check the log window(in Menubar Windows->Create log window) and check if any error related to denoiser got logged?

Thanks,
Vijay

Hi,
no issues here with Enterprise, or Studio 2021.1 and AI Denoiser, with RTX 3060:

Please, download and run GPU-Z:

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


ciao,

yeah i don't get why this isn't working...

just to be sure i swapped the 3060 for a 1070 and the issue is the same

here is GPUZ:

the screenshots were taken after the first denoiser run. IOW i opened Studio 2020 and 2021, loaded the scene in each, started the render and then once complete switched to Denoise pass

as the screenshots show, 2020 has some data to work with but 2021 does not

Weir, I have the same Nvidia Studio driver version, only not DCH:

What about the Win 10 version?

What processor do you have? does it support AVX instructions?.

What processor do you have? does it support AVX instructions?.

this must be the problem

i have an i7 990x which i don't think supports AVX

is there a way to enable? or more likely it's time for me to finally upgrade
