I've been trying to use Lightroom's subject and background detect feature, but I constantly have been getting an error telling me that they can't be detected. As well as get very noisey images when attempting to denoise.

    Thanks! It was a driver issue with the old driver.

    Got an update from the work admin, and now it works!

    Hey, @42780231. Welcome to the Lightroom Community. Thanks for sharing the System info. Your machine has two GPUs: the power-saving Intel XE Graphics and the high-performance Nvidia RTX A1000.

    Please try these two suggestions:
    1 - Update the graphics drivers using Intel's and Nvidia's auto-detect programs. 

    2 - Follow step 6 in the content here to configure the default GPU for Lightroom: https://adobe.ly/49YQSCI

     

    After you update the GPU drivers, you can just try the steps below and check how it goes. The GPU info & Logs location on Windows is %APPDATA%\Adobe\CameraRaw. A shortcut to get to this folder on Windows is:

    • Press the Windows + R.
    • Enter %APPDATA%\Adobe\CameraRaw

    • Rename the GPU & Logs folder in this directory by adding .old at the end. (GPU.old & Logs.old)
    • Relaunch Lightroom.

    Let me know how it goes. Thanks!
    Sameer K

    Hi, we're sorry about the trouble!

    Are you experiencing this behavior with all the images? 

    Please go to the Help menu in Lightroom, then System Info and copy the text. You can either paste the text as a reply here or in a text file and share the file with us by attaching it to the reply. 


    Thanks,
    Nikunj

    Returning to Lightroom 8.1 fixed the issue, I'm assuming the update might not be compatible.
