Convert to DNG in 13.0.1 is very slow, CPU/Memory intensive and crashes

I have been scanning old negatives with VueScan, converting them from Negative to Positive in LR for nearly 4 years now.  The last step in my process is to convert the files to DNG in LR.  Since 13.x this step has slowed to a crawl and even crashed LR (sent a bug report to Adobe when it crashed).  

 

I select a group of photos to convert (10-20) to DNG, I then watch high utilization and memory usage jump from about 10gig to 36gig or so. Converting 10 images in the past took maybe a minute.  Now it's at least a minute for 1 file.  I made an attempt to convert 22 files this morning, LR crashed after about 18.

 

I have tested this with no other apps open, without GPU acceleration with the same results. Something has definitely changed in this version.

 

Has anyone experienced this issue?

 

The other bug I have is dual monitor zooming in Develop mode, something I use every day, now broken. This has been acknowledged in other posts here. Another bug dealing with plugins was quickly fixed in 13.0.1. Terrible update as far as I am concerned.  I have made too many changes to my catalogs in 13.x to try to go back to an older version.  The quality team has serious work to do.

    My Lightroom version 13.1 on mac uses really high cpu (~600%) is really slow (see attachted) screengrab from activity monitor.

    What is the problem with this? It used to be fast and take a small percentage of my cpu.

    I am only importing NEF files from a Nikon D810 and converting them to a dng.

    Hi Guys.

    Was having some more "SLOW" issues and went looking for fixes.
    I came across this in Reddit and I will say it has actually helped.
    (Not my solution but sharing is our best way to help everyone.)
    Give it a shot.  See below.

    Cheers Doc

    "I think I may have found the solution. After doing all of the suggested things to no avail, I searched hours and hours and found a reddit thread that had a solution with someone else with a high end pc but lightroom being super slow. This worked for me. I went to: C:\Program Files\Adobe\Adobe Lightroom Classic. Then in that folder, I right clicked the lightroom.exe file and selected "Properties", I then went to "Compatibility" tab. I then clicked on the "Change high DPI Settings" button. From there I went to the bottom where it says "high DPI scaling override" and clicked checkbox for the "Override high DPI scaling behavior" and changed the dropdown to "Application". I clicked OK then Apply. I restarted lightroom and it is running normal now! Thanks for eveyones help and kuddos to the random reddit stranger that posted the solution to this."

    That's a potential fix on Windows, not Mac.

    I have been exporting original camera raw files as DNG's to send to 3rd party editors for years. This has always been super fast. Since the update to LR 13, it has slowed to a crawl. In my case, it does not crash LR, nor does it seem to use a particularly high level of computer resources (I still have 50% of my RAM unused, CPU utilization is <20%, HDD usage is intermittent and minimal, GPU usage is indistinguishable from 0). And export of ~50 files that used to take about a minute now takes 5-10 minutes. No other system change on my end aside form the progression of LR to version 13. This definitely feels like a real problem.

      I'm also experiencing this. My typical workflow has slowed to a crawl and this is on a M2 Mac Studio with plenty of room. 

      it appears the convert to DNG process is single threaded, but even at a single thread it doesn't seem to be running properly, or gets deadlocked with the sync engine?

       

      Adobe, can you please address this? Lightroom classic eventually crashes on exit, and I've filed all the crash reports.

      Just scan to TIFF and forget using DNG format, it does nothing for you. I have an Epson Photo scanner and Vuescan and just save to TIFF which is perfect.

      OH and FWIW, a DNG is a fully-compliant TIFF file. What you are seeing is a byproduct of trying to batch compress huge files, your are probably running out of memory. Can you run them through Photoshop and save out to a compressed TIFF?

      Initially it was maxing out my 64GB of RAM and 100% CPU.  After uninstalling/reinstalling LR per Adobe's request that no longer seems to be the issue.  Memory sits around 65% when converting.  Sometimes converting just 1 image causes the crash and utilization is not high.  Also, just the DNG converter with the latest Camera RAW selected will crash, though the 14.x version will complete properly.

      I'm not sure on the scanning etc, however I can confirm there is most certainly an issue with speed in this version.  The upgrade to a new dB version has killed any speed lightroom had in the previous version.

        I am experiencing this problem now. my typtical import process on my older intel imac was 8x faster than a brand new Mac Studio (M2).

        Did you migrate your apps from the older computer or reinstall from scratch?

        We’ve reviewed the email address you use with this forum and find no crash reports in our system.

         

        Did you see a crash dialog?

        Do you use a different email address when filling out the crash report?

        Was the crash dialog Adobe’s? Microsoft’s?

        FWIW, I convert to DNG daily and have done several batches of 100 or more in the past 2 weeks with no issues with regard to speed or stability.

        I just had it crash again trying to do 10 images.

        I use a different email address though I don't think it is wise to post that in a public forum. 

        It is Adobe's crash dialog. 

        I am sure I will have it happen again today if there is anything you want me to do to diagnose it.  Again, this has been a routine for me for four years, this issue started with LR 13.

        These files I am converting are very large, that is the whole reason for the conversion 400meg out of Vuescan, about 25meg after conversion. Maybe that size is the difference in your batches to mine?

        Thank you for your response Rikk!
