Corona 4 DailyBuild Denoiser CPU AI test :)

[ErfanSadat]

Hello everyone .

this is my last visualization . kitchen concept . my main purpose in this visualization was testing the corona 4 daily build CPU AI DENOISER and also messing with corona light mix a little bit .


hope you like it

software : 3dsmax - corona 4 ( DailyBuild ) - Affinity Photo

Curious to know if you were able to draw some conclusions about Intel denoiser from your tests? How do you find it against Corona denoiser, or against Nvidia denoiser?

If I wanna be honest with you, I guess we still need to wait for the corona 4 final release because everytime I tried to test the CPU AI DENOISER ( especially in high resolution renders ), it just made my system freeze and I had to shutdown the whole system and try again . but it worked in some cases and I have to say that is so powerfull cpu based desnoiser which gives you the speed of Nvidia denoiser and Also the quality of the CORONA HIGH QUALITY denoiser .

That's interesting. My findings were quite different. I had impression, that Intel denoiser is significantly slower than Nvidia's one and it gave much worse quality compared to Corona denoiser. I was testing one of the first build and never returned to it, maybe now its implementation got better? I probably should give it another chance :]

no Idea :) ...maybe it acts totally different on different scenes ...as I mentioned, it even makes your system freeze in some situations ...I think we need to w8 for the final release ...

Hi!

Could you open a bug report via ticket or separate forum thread on freezes? I don't think we've had any reports about the CPU denoiser doing that (btw, are you sure the NVIDIA denoiser was unchecked for "during IR"?). https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max for how to report the issue.

On results, the Intel denoiser should always be significantly slower than the GPU denoiser, but faster by a little bit than the Corona Denoiser. Quality on the Intel denoiser is, like the NVIDIA denoiser, not as good as the Corona High Quality (as our denoiser uses additional data that those two alternatives do not). Because the Intel denoiser doesn't use all the data that the High Quality one does, it does use slightly less memory (not a huge amount, but some).

Its strange for myself too...cause I used CPU UI denoiser before and it worked very well on the scene that I was working on before ...but recently I can't use it ( I think it's gonna freeze on the high resolution renders ) ...and honestly I can't gives you any information or crash report cause not only my 3dsmax freeze, but also my whole system is gonna freeze ...the only option that I have when it freeze is pushing power button and shutdown the whole system....

and of course the quality of the CORONA HIGH QUALITY denoiser would be much better and I just said that CPU denoiser quality is something between corona high quality and nvidia denoiser quality....I didnt say that they're exactly the same :)

Version I used In this test was :

Corona 4 - daily build - 20/02/2019
and
Corona 4- daily build 22/02/2019

Hi!

Still would be great to have this ticketed or forum posted as a bug - developers and support won't see it / find it to reply to it under a Gallery entry, and it would be good to find out what is happening. Please do report it so that we can investigate and resolve it for you.

Thanks!

Sure I'll do that .
tnx for the support

Thanks! I know it takes extra time to report it separately, but it's a huge help to us in tracking it, and replying to you - so we appreciate you doing that!
