Question

Denoise AI takes 10 minutes to render

I was so excited to update ACR, but denoise AI is unusable for me. I'm running a Windows 11 with 64 GB RAM, 2 solid state drives with 1 TB each, one of them empty, and my GPU is NVIDIA GTX 1060 with 8GB memory. ACR is set to use GPU. PS and Bridge run fast, but the new feature, Denoise AI takes 10 minutes to render. I thought it was a mistake when the display said 10 minutes, but it's real. Ten minutes is unusable, not to mention that the result, after waiting 10 minutes was poorer than Topaz denoise, which renders in less than 20 seconds. What's going on? Have I gotten a defective update? I've been reading that other users are running into the same problem, but one user reported a much inferior GPU  than mine. Do I have to buy a server to run ACR denoise? If so, it's really unusable.

Hi All

I noticed a post from Rikk Flohr ( apparently "Adobe Employee") = saying that Adobe's Ai NR takes "6.5 Years old home-built system with GTX970 - 4 GB Card takes <90 seconds for a Canon 5D Mark IV file."

Got me curious - I have a discrete GPU nVidia GTX1070Ti w/8Gb and most recent nVidia drivers ( not gaming versions ) installed.... the card works w/o issues with ACR and DxO PL6.* ( DeepPRIME XD) - however it takes 10-20 times longer than DxO NR for Adobe's NR.... and yet my card is "better" than Rikk Flohr's... so where might be the problem.... I was assuming that Adobe's Ai NR is using Tensor Cores on nVidia GPUs and in the absence of them it will be way-way slower  but the claim from Adobe employee that his way older card ( also w/o tensor cores ) can do AiNR for 30mp raw file in 90sec is ????

I downloaded ISO12800 Canon 5D IV raw from Imaging Resources to RAM disk (not even SSD but to RAM disk)

ACR time = 8 minutes for Ai NR ( for comparision Adobe's enhanced details Ai-Demosaick is 2 seconds )

So what I am missing ?!

The topic with the claim was locked  = https://community.adobe.com/t5/camera-raw-discussions/denoise-ai-takes-10-minutes-to-render/td-p/13750965

@deejjjaaaa 

 

Here's what I suspect will be typical timings for an *old* but otherwise decent GPU.

 

The one in question is a Quadro P2200, 5 GB, released 2019, but originally released as P2000 in 2017.

 

36 MP - 1:56

43 MP - 2:15

60 MP - 3:12

 

Other megapixel sizes can be extrapolated from those numbers, as it seems roughly proportional. 30 MP, for instance, should land at about 90 seconds.

 

This is all around 6 x slower than my other machine with an RTX 3060, which finishes 60 MP in 33 seconds.

    but that does not answer a question 
    Rikk Flohr ( apparently "Adobe Employee" - which matters as he might know more than us ) = saying that Adobe's Ai NR takes "6.5 Years old home-built system with GTX970 - 4 GB Card takes <90 seconds for a Canon 5D Mark IV file." and my card GTX1070Ti (w/ 8Gb) - which is a generation newer ( and class - as "Ti" - better , and twice more memory ) with most recent (non gaming drivers) from nVidia on such raw files clocks 8 minutes with Adobe's Ai-NR ( but 2 seconds with Adobe's Ai-Demosaick - which kind of shows that my GPU works OK otherwise ) and GPU monitor shows that GPU utilization never goes above 12% and mostly stays under 5% during those 8 minutes... so how come his GPU does 5-6 times faster than mine... there is something a·miss on Adobe's side here - may be he can comment which driver version he uses - unless as Adobe employee he happens to use some next non public not yet released version of ACR already with something already fixed

    comparing with Quadro cards is not proper

    his vs mine are better comparison 
    GTX970/4Gb vs GTX1070Ti/8GB
    90 sec vs 8 min

    definetely something is wrong 

    He said "I would recommend some basic GPU/Driver Troubleshooting to find where your bottleneck might be. " - OK, may be can tell the exact version of nVidia drivers he sports and also confirm that he clocked on publicly released ACR/LR version

    It's your GPU.

    So I was right. I need a server or something that costs over $10K. Thanks a lot. As I said, the feature is unusable.

      No, you were not right. 

      For $10K, you can buy three MacBook Pro M1s like mine that process a 24.4MP raw in 12 seconds. 

      And no, the product isn't unusable as you define your issue. It works; it's too slow for you. Big difference. 

      But yes, your old and outdated GPU is why you can wait 10 minutes, not use the new feature(s) or work with a different product. 

      For others who may view this, the bottom line: 

      Eric Chan says you probably ought to use 8GB for Denoise.
