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

I apologize for making my initial statement unclear. When I said I swapped the GTX 1660 for the A770 and experienced the same problem, I meant that I replaced my working GTX 1660 with the A770 and then started experiencing the same problem as the other folks posting here. The GTX1660 worked fine; it was just too slow. As I said previously, the fact that the failure occurs with both Lightroom and DXO DeepPrimeXD makes me believe the problem is in Intel's drivers. I just installed a Zotac 3060 GPU and it works fine with both LR denoise and DXO deepPrimeXD.

Um. I don't know if the issue belongs to Adobe or Intel because  equivalent "denoising with AI" from other brands (I mean DxO or Topaz) is working fine with the ARC 7xx. But, you are right, I hope there is already a thread of dicussions somewhere on the Intel side . As far I know, nobody  from Adobe is reacting on this forum since long time while the issue is major :  this issue is major and stake becomes huge with the context:  on one side Intel just launch  big promotion campain to come back in the market of CGUs, on other side Adobe create a game changer with the embodiement of AI in LRC and with Firefly in PS! A conjunction which can create a big disappointment from photographers who need to upgrade their PC right now ! It was my case few weeks ago ( (see my previous post from 14th of may) and I , by chance, it was not too late to change my ARC770 with a RTX3060/12Go for the same price (and I saved 35$...) . Very bad deal for Intel....

your statement "I just swapped an Nvidia GTX1660 super for the A770 16gb and experienced the same problem" to me clearly suggests that it is not and Intel problem since an Nvidia GPU has the same issues.

I agree with the previous PatGarrett post up to a point, but since LR denoise works on all of the other brands of GPUs out there, I think in this instance the problem belongs to Intel.

Topaz gets he job done correctly and quickly.  SW needs to be designed so that it works on a broad collection of common hardware.  As a former QA manager for a SW company, there are times when you need to adjust the SW to run properly on certain hardware (in this case maybe just using the CPU rather than the GPU).

I think that the fact I was able to get a similar failure using DXO Photolab DeepPrimeXD clearly suggests the problem is with the Intel drivers, since that's two different software products that are having a similar failure. I need a GPU that works right now, so I have ordered a different card and am in the process of returning the A770.

I have a new Lenovo Slim 7i laptop computer with Graphics Processor Intel Arc A370M. I use Adobe Lightroom Classic for processing raw (Canon CR3) photos. Today I used the AI Denoise function for the first time on this computer and the resulting .dng was brownish/black and white, no color in the photo, and dark. Sounds like the same GPU issue as others have stated in this thread. I hope this problem will be fixed soon.

I just swapped an Nvidia GTX1660 super for the A770 16gb and experienced the same problem. Then I tried the other software I sometimes use for noise reduction. Topaz Denoise and Photo AI work fine, but DXO DeepPrimeXD has a similar dark screen result. So I think Intel has a major driver problem with some of the photo denoising products. One thing that might be pertinent is that both Lightroom Enhance denoise and DXO DeepPrimeXD do their denoising as part of the demosaic process. Of course that doesn't explain why DXO DeepPrime works OK.

I have the original drivers provided by Asus. The newer Intel drivers would cause Photoshop to freeze and become unusable. Since I just bought this, and can't afford a new one for at least another year, I may have to switch to something besides Adobe.

I'm guessing you updated the Intel driver or it automatically updated.  If you roll it back, you may be in luck.  Otherwise, like the rest of us, you'll just have to wait... or but an Nvidia GPU.
