P: (Windows - A750 & A770 GPU) New Denoise turning images black and white

[anthonynowack]

Using the new AI Denoise feature seems to darken my images and strip almost all the color out of them. Files are from a Nikon D500 being processed by a Ryzen 5 3600, 32GB RAM, and Intel A750 video card on Windows 11. Tried to create virtual copy of file and reset all other adjustments and it makes no difference. Still dark and almost completely black and white.

Same problem here  , with brand new Pc- Intel I9 13900, 64 Gb ram ,Intel arc A750, Win 11 Pro. Images turn dark b&w when applying  new Lightroom Denoise AI.

Sorry. Should be fixed now.

I'm having the same problem with Denoise making black & white images. It's also taking a ridiculous amount of time (50+ minutes). I am running LR on a Lenovo Yoga 7i but my laptop has a GPU Intel Arc A370M. Is there any progress on this problem?

Same issue with Denoise here:(

Windows 11 10.0.22621 Build 22621

i7-12700H, 2300 Mhz, 14 Core(s), 20 Logical Processor(s)

Arc(TM) A370M Graphics, Driver Version 31.0.101.4335

Thank you for sorting this out for us!

Hi All, 

I have a poor but workable way to get Denoise running and giving amazing looking, but somewhat slow results. This is a stop gap method that I used to get my system working much better until the drivers get updated, it may or may not help with yours... try at your own risk...

On my i7 with the Ark A370m GPU I was able to get proper colors by disabling the driver for the A370m in the device manager. I also turned the GPU to "AUTO" in the performance tab of preferences in Lightroom. Interestingly, the GPU is still listed and you can still see it taking load when processing pictures. 

After a system restart Denoise is now working properly and giving a ~3 minutes processing time estimate/ picture, it was 30+ minutes with the GPU driver enabled (and the output was all BLUE!). 

Export processing times are also not to bad, ~30 seconds to output 50 edited pictures at 100% jpg quality. This is similar to times with the driver enabled.

I hope this is helpful and I really hope we have proper drivers very soon!

Lightroom ROCKS!

Thanks for the workaround suggestion, but I'm reluctant to muck around in Device Manager. What will disabling the GPU driver do to overall LR performance? Or the rest of my laptop for that matter. I suspect it won't be good. Also, disabling the driver in Device Manager is not straightforward. Is the procedure: Device Manager > System Devices > Intel Graphics System Controller Firmware Interface > Driver tab > disable. Then reboot? What about the Intel Graphics System Controller Auxillary Firmware Interface? So I do this, use Denoise, then go back to Device Manager and reenable the driver, reboot, etc.? Hello Adobe, do you have enough info to fix this now?

Hi Rick,

Here is a screen shot of how I disabled the ARC GPU on my machine. It is actually very easy, just click "disable device" and reboot the system. I do totally understand your reluctance to modify settings, for me I needed to finish a project and this got me back up and running.

If you do this, my understanding is that the ARC GPU will no longer be active. You will be using the video capabilities built into you system, for me this is the Intel Iris Xe integrated graphics controller.

For lightroom, I am actually seeing the same, or slightly increased performance by turning off the ARC GPU. I think this is because the integrated graphics controller is fairly decent and working properly with LR. The more powerful ARC GPU is not functioning properly so it is not accelerating anything that I can see in LR, just getting in the way. I have not tired it in any other Adobe programs, so I cant speak to how it works or not with those.

As far as the other programs that are GPU intensive (video editing, gaming ...) and it is working properly, I am sure it is a big hit in performance. For everyday computing the integrated graphics controller is all most people have, so it should be fine.

Also, I am not sure if the system reset is actually needed after disabling/ enabling the driver, just a habit I have from a different century:)

I hope this is of some help.

Disabling the ARC GPU won't be a good idea for those who do not have an alternative integrated GPU on their mainboard.

For those who do have an alternative GPU, disabling the ARC GPU in Device Manager may not be necessary. You can use Windows to set the GPU that LrC only will use:

1. Open Settings > System > Display.

2. Click Graphics settings.

3. Under Graphics performance preference, ensure Desktop app is selected in the Choose an app to set preference selector, then click Browse.

4. Navigate to C:\Program Files\Adobe\Adobe Lightroom Classic, select Lightroom.exe and click Add.
5. A panel will display for Adobe Lightroom Classic with buttons Options and Remove.
6. Click Options and choose the integrated GPU, which is likely to be the Power saving option and Save.
7. Close settings. No reboot needed.

Now LrC will use your integrated GPU while everything else will use the ARC GPU.

When this issue is fixed, go back to the Graphics performance preference and Remove the Adobe Lightroom Classic preference.

My only concern is that LrC has some very serious problems using Intel Integrated GPUs - my own always fails.

Thanks for the response - the screenshot really helped. You were right - it was easy! Got Denoise working.

[PatGarrett]

The workaround seems a poor idea. I'll continue to use Topaz Ai Photo
until LRC is fixed which works well and quickly with no modification to my
drivers.

A really poor idea is exposing your phone and email address to the web spiders. You might consider editing your post.

[PatGarrett]

Not sure how to remove it. I would like to. I didn't realize that my email
suffix was added to the post.

[Rikk Flohr: Photography]

I removed your personal details.

I feel the same.  I'm a photographer not a gamer.  The reviews we read are all about gaming.  Yes, with LrC's AI Denoise, it's whole new ballgame.  My meagre understanding is that AI processing is heavily depenent on tensor cores.  The Arc A750 has 448 tensor cores, the RX 6600 none.  So, the RX 6600 might have the edge for gaming but I think it would struggle with AI Denoise.  Having said that, there is a serious issue with Intel Arc GPUs and Denoise but I'm hopful it will be resolved with a driver and/or software update, so I would hang fire for the moment.

I decided to go with the Arc 750....few issues so far. Only  weird behavior is it's idle power consumption of around 30 watts....luckily electricity is cheap where I live, would be a different story in Europe. I just power off when not using the pc, it boots fairly quickly.

[Bob Trlin]

Same.  AI Denoise works fine with my integrated Intel UHD Graphics 770 albeit it takes 4 minutes.  The big difference is that the iGPUs don't have tensor cores, the Intel Arc discrete GPUs do.  I'm guessing that's one reason why they are so much faster.

[mr francois]

I have same problem here with my CGU Intel ARC 770. I understood you have sufficient data and don't need Dxdiag log anymore, just tell me if you need.

So, i am just waiting for a new release of LrC 🙂

[Bob Trlin]

I'm seeing a lot of posts elswhere about problems with running LrC AI Denoise on an Intel Arc GPU.  What I don't know is if this is a general problem or rare.  I haven't read of anyone claiming they are running AI Denoise with an Arc GPU without a problem.  Has anybody?
