Lightroom Classic: GPU acceleration enabled slow/lag in Develop when zoomed at 100%

Hello,

I am experiencing an issue with lag and slow movement of a picture inside zoom in develop panel. I am building 1:1 preview.

Solutions tried:

  • Remote session with Adobe engineer confirmed as a bug or issue
  • Reinstall GPU drivers, full accell enabled
  • Issue only in develop module, in library movement is nice and smooth in zoom
  • Issue only 10.3 with GPU enabled
  • No issue in 10.3 with GPU disabled
  • No issue in 10.2 with or without GPU enabled
  • Reinstall version 10.3 several times, I am running back 10.2

No problem at my end as I have 12CPU, 32Gb RAM, 1070ti GPU - the latest drivers

Zooming ist very jerky on my system, as well. 10.2 and also ACR are perfect.

You haven't mentioned resetting your preferences - they survive an uninstall/reinstall -

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Does the behavior continue after resetting the preferences?

I did that, it is still the same.

Double check this setting:

NVidia

1.Go to NVIDIA control panel > 3 D settings > manage 3 D settings.
2.Program settings > add the .exe file of the app > set the power management mode to prefer maximum performance.
3.Click on Apply, close the control panel, launch the app and check if it helps.

Tried this also. No luck.

The next step I would recommend is a clean reinstall of your video drivers - make sure you are getting the latest drive from nVidia's site and not Windows update - as the WU lags a few versions behind.

A clean GPU driver installation won´t help, Rikk. My system is a brandnew installation with the latest nvidia drivers.

The problem must be in the code, because earlier LR versions were zooming perfectly smooth.

I got my new PC couple days ago and I face this problem in Lightroom Classic 10.3, panning lags at 100%, any idea how to fix it or what seems to be the issue?

I have to mention I have Windows 10 Pro with all the latest updates installed, latest Nvidia drivers and Adobe Light updated, not sure what I can do to fix it.

Please don't be insulted by this question but did you go into the Preferences, Performance tab and activate the GPU? I've never found a pattern but installing Lightroom doesn't always activate the GPU. I've even had an update turn it off though that only happened once.

Yes, did that plus some other suggestions like enable high performance for Lightroom app.

Have you tried reverting to a previous NVidia driver to see if the issue is the same or different?

I was on old Nvidia driver when I faced the issue, I updated the driver to the latest version yesterday, nothing changed, also changed the power plan for Lightroom on high performance, nothing is helping, strange part is that in happening only in Develop mode, if you switch to Library mode and zoom in 100% and drag, its working smooth, I feel like it's Lightroom related issue since its working on Library but not working on Develop mode.

Update driver didn't help and it was the first workaround I tried. All started with LR 10.3. I also searched google for any advice, so I tried these general recomendations, like high power for GPU or reinstall LR etc.

Hi,

I also face the same issue: only in develop module when zoomed in to 100% (And dragging the image around) I observe massive stutter & lag with GPU acceleration enabled. I also tried to solve the problem with the steps mentioned above & in the performance guide with no change to the behavior. I installed Windows 10 fresh recently incl. all latest drivers. If I disable GPU acceleration the issue goes away! But the overall performance in this case (e.g. changing crop borders & applying healing brush) is sluggish (compared to my MacBook Pro). I am using RAW images from a Nikon D850.

My specs:

5900x

64GB RAM

3080 Ti

Samsung 970 Evo SSDs

Running latest Lightroom Classic Version 10.4 on latest Windows 10.
