High CPU with Camera Raw Denoise - Part II

[Redcrown]

The following video is a demo of the CPU usage of the latest version of Adobe Denoise AI on Windows 11. There is something strange in that Adobe Camera Raw runs the CPU in the high +90% for a long time after all the Denoise work is done. If you have ACR Version 17 with Technology Preview enabled, please run a similar test and report if you see the same strange CPU usage.

P.S. I would also appreciate comments on the audio quality of the video. I have common old age hearing loss, so I use special speakers and a graphic equalizer to optimize audio for my old ears. I've also implemented custom settings in the OBS Studio screen recorder that are supposed to optimize audio quality. I'd like to know if it works for normal ears. Is the audio level OK, and the sound clear and understandable?

Bugs should be reported to Adobe.

Bugs should be reported to Adobe.

Been there, done that, many times over many years. Never with any luck. Most recently in response to an Adobe Forum post by employee Rikk Flohr asking for feedback, none of which was acknowledged.

I imagine Adobe pays little attention to single, unconfirmed reports. That's why I'm seeking confirmation (or denial). Still baffled that nobody else has been willing or able to do a 5 minute test, followed by a 1 minute reply.

If this is a true bug and not just a gremlin unique to my system, I think it's pretty serious. On a laptop system it could quickly drain the battery and overheat the CPU.

I don't use the software, so this is the only thing I can respond to.

I don't hear high frequencies so well anymore myself. The sound is fully understandable, but the bass is very heavy and there's lots of rumble when you're speaking. That disappears during pauses, which indicates that active noise reduction of some sort is at work. I much preferred listening to the audio with the bass turned down.

With my i9-1350HX and Nvidia RTX 4000 laptop GPU (profession version of laptop RTX 4080,) denoising 45MP file:

During denoise the GPU goes up to about 92% for the duration of the denoise about 10sec. There is a very quick short peak in CPU immediately after the end of denoise 42% for one reading the rest are very low.

What is your CPU?

KajE,

Thanks, and congrats for being the 1st of 13 to actually do the test. And it seems we are on to something as you say your system does NOT suffer the long, high CPU % after the denoise is apparently complete. Different CPU (I9 vs my I7).

Can you please confirm, what happens when you re-open a raw file in ACR that has already had denoise applied? Does the CPU do anything unusual? Normal would be a brief period at 20% to 30%.

I hope I can get more testers to help narrow this down.

I periodically monitor GPU and CPU usage in image processing programs and never noted what the OP described with denoise in camera raw.

I just did a quick check applying denoise to two iSO 6400 m43 raw files in 16 bit Prophoto. Technology preview seem on in the preferences. Latest and greatest version of Camera Raw.

This computer is "just" a 12th gen desktop i5k and the GPU "just" an AMD 6600. It would help to know what the OP was using.

The GPU use spikes up on the Task Manager monitor during the process, the CPU lopes along, never hitting anywhere near 100% even for a fraction of a second, hardly hits double digits % use. When "enhancement" is complete both go down to baseline, didn't time it but way less than 30 seconds in all. That is what I have always observed. I do not and have never seen anything like what I see in the video on this or other desktops.

Don't use laptops for serious image processing, as in don't own one powerful enough.

Sorry, didn't turn on audio for the linked video.

Like many of the vexing issues we all experience too often with Windows and Adobes, sometimes daily, they may be peculiar to particular hardware and software environments. While we are perpetual beta testers for Microsoft and Adobe I can't reproduce what the OP experiences.

Opened the denoised file. This time watched in task managers performance tab. Shortly after opening the file there is again the peak on CPU the graph actually reaches 100% for an extremely short time (the number displayed for a couple of tires varies between30 and 90%, because the peak is so short). Otherwise there is a ca. 20% for a few of seconds around the peak mostly after.

Thanks all. I now have 2 reports that contradict my experience, so it's a system dependent issue. That's very helpful, but not much I can do but wait for future updates to see if things change.

I've made changes to my Windows OS -- debloating, disabling useless services, etc. All from well known, trusted sources. And I've never encountered such a system dependent issue before, but who knows. The complexity of modern systems + compute intensive AI software opens such possibilities.
