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

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.

    It might be helpful to the team if you made the Denoised DNG avaliable to Rikk so that the end result can be examined.

    When I use the new denoise setting my images come out several stops darker. If I then increase the exposure of the resulting DNG file it looks like the file is lacking some colors (mainly reds). I tried turning off GPU acceleration in preferences but no change. Its doing exactly the same thing for my Nikon and olympus RAW files. Help?

      Do you have an Intel A750 GPU?

      Did you use the Enhanced/Denoise early in the post processing, or after some Masking?

      Did you apply some tonal edits, especially Shadows, Clarity, or Dehaze prior to Enhanced/Denoise?

      I created a virtual copy to reset all the adjustments and delete any masks. I also tried it with a file I hadn't done any adjustments to and it had the same result.

      Please give us your system stats including GPU Memory. 

      To troubleshoot: 

      Go to Edit>Preferences>Performance tab and set your GPU to Off. Restart Lightroom and Enhance the same original as before. It will take significantly longer but should show if the GPU is suspect. Any difference?

      If so, I would start looking at your video drivers. How old is your current driver? What happens if you update it?

      8GB RAM on the A750. Disabled the GPU as you described and it made no difference. Same result. I am running the newest stable driver from Intel.

      Can you share one of the original raw files that exhibits the behavior?

      This is the last piece to my new i7 13700, Z790 Gigabtye Elite AX & 32 gb DDR5 photo editing build.

      I need a GPU for a photo editing build using Lightroom/photoshop. It will do NO gaming and NO video editing.

      So I read a lot of negative reviews/remarks about the A750 with respect to gaming performance. Is that irrelevant for LR/PS use? Should I care if it can't run certain games that I never heard of before? or would it impact my use of Lightroom/photoshop? I also wonder if there is even more improvement upcoming as they continue to refine the drivers?

       

      If people are having issues with the Intel Arc A750 I can get a comparably priced RX 6600. Both of these GPUs are on sale for roughly the same price. I am aware that LR is starting to leverage the GPU more but my usage doesn't require it. I do use the sky selection tool but don't want to pay  several hundred dollars more to shave a few milli-seconds off of that selection. And I use a 1440p monitor, not a 4K+ monitor.

        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.
