Question

GPU acceleration causes oversharpened look in develop module

Hello fellow Lightroom Classic users,

 

I have observed the following issue in Lightroom Classic 9.3 on a Windows 10 Pro machine using an ATI Radeon RX580 graphics card.

 

Images look "fine" in the library, but heavily oversharpened in the Develop module.

I have encountered such an issue for the first time a few months back and got the tip to purge the Camera Raw Cache, which solved my problem back then.

 

However, the problem has come back and the purging does not solve it anymore.

I have found out that if I disable GPU acceleration in Lightroom settings, the images suddenly look fine and the oversharpened look can be turned on and off with the checkbox for GPU acceleration.

 

Maybe this information is useful to someone else.

 

Best regards and stay safe and healthy,

Jan-Hendrik

Hello! I had the same issue as you.

To me, what fixed it was disabling my GPU's image sharpening feature. In the Radeon Software Control Pannel, go under settings (the gear icon), graphics and make sure Radeo Image Sharpening is off. Since only the develop module uses GPU to render, it makes sense that only the develop preview was over-sharpened.

Hopefuly this helps some of you!

    Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

    Hello again and I apologize for getting back on this so late.

    Here is the system information. As I am German, my system language is also set to German. I hope the information is useful, anyway.

     

    As I have stated above, the problem is gone once I deactivate all hardware acceleration options in Lightroom.

    Once basic acceleration is switched back on, the images get that oversharpened look in the Develop module.

    I would recommend reposting this in the Feedback forum so that the Adobe engineers see it.

      Use Graphics Processor in /preferences/performance/  should not be affecting edits.  Oh, it might provide a performance improvement while accomplishing some edits, but not affecting results.

      Now, depending on how old a GPU is, how capable a GPU is, and what driver you have, this option can foul things up. And if you are not running 4K, will not improve much.

       

      Perhaps this option does not work well on your computer and should be disabled?
