P: Progress bar displays inprogress long after the DeNoise command has completed creating a file.

I would like to get some feedback on  the follwing issue.

USed H/W: HP Z6 G4, 2 CPUs Intel 6136 Xeon3.0 12C

128 Gb of RAM

GPU Nvidia RTX 4070 ti Super

Primary disk 500Gb SSD and 2TB SSD gen 5.

Windows 11.  64 WKST Plus

Issue: DeNoise , "Lightroom not responding"

Example: Denoising a Nikon RAW file from Z9.  (Size ~55Mb)

Lightroom Denoise estimates a 7 s process time.

This fits well with the time the GPU is active and staying at about 90% usage.

Once the GPU stops after 7s the systems seem to be idling for time of 2 minutes before it has completed

the task and returned a DNG file to my disk. During these 2 min the message the message "Lightroom Framkalla Not responding" apperas at the top of the Lightroom window.
Have also run a test by selecting 16 RAWfiles and recorded times. Result The GPU runs for 4 min and 36 s ( It seems to run one RAW-file at the time at a similar GPU time of operation (7 sek) but also a short paus between each  RAW files processing and once all RAW files is processed in the GPU (time 4 min 36 s) it then once again gets into the "sleep mode" and message "Lightroom framkalla Not responding" pops up again. This sleep mode goes on for 25 min and 46 s.  Which menas the 16 RAW files is returend after a total time of almost 30 min.

One final note: Durin the "Sleep mode" the CPU in the one file example just idles around 3-4% while in the 16 file example the cPU idles around 5-7%

I have no idea what's going on here - but this is when the Denoise process itself is completed, and LrC is writing a linear DNG and saving it to disk. That's where it stalls, and that's where it differs from ACR.

So  why does LrC have problems writing/saving a linear DNG? Is "GPU for Export" failing, and if so, does a standard Export work as expected? Is there anything else on your system that takes a long time to save? What is the disk configuration it's saving to?

I am unable to download the file - "Max Downloads Reached"

Ok Rikk,

I will put it up again this evening and hope you will beat any body else to it since it is a onetime download.

A one time download link on a forum with hundreds of visitors per day is unlikely to be available to your intended recipient. Ideally, you should use Dropbox or similar.

Hi Rikk,

Hope it works this time. Link below

I have the file - thanks.

The team is investigating this issue which appears to be a progress bar fault and not a fault in the actual DNG creating. I've cross-referenced this thread to the existing bug. 

Thanks for the sample file. 

[Torleif34303611pu33]

Thanks a lot Rikk,

Make sense, I believe I also noted similar behaviour when testing "Super Resolution". Progress bar hesitating for quite a while when it indicated approx 80% ready.  (Equal to the screendump I enclosed earlier in this thread)
