Lightroom 9 very slow during crop with GPU support on

[sandroriz]

Today I upgraded my LR CC Classic from 8.4.1 to 9 and I had a bad suprise.

When I draw the crop rectangle, the mouse moves very slow and with a lot a lag; minimal movement are impossible because of the lag. Same thing drawing the lines of the Upright Guided command when the zoom popup is on, or painting with the Adjustment Brush.

Setting OFF the use of the Graphic Processor in Preferences, works much better (but obviously not so fast like before).

I have updated all the video drivers (nvidia quadro P2000 version 441.12 and Intel Graphic 630 version 26.20.100.7372) without results.

Am I alone with this issue ?

Dell Precision 5530 with i9; Win 10 1903

Thanks

I have got similar problems with Lr for a last few weeks. Sometimes it makes impossible to edit any picture using this program. Constantly getting freeze, lags make my job impossible to finish at the moment. I tried a few things to sort it out but I have not noticed any improvement. 

Today I upgraded Lr to version 9 but it works exactly the same or even worse!

Hi there,

We apologize for the issues you are facing with using Lightroom Classic on your Dell Precision machine.

Would you mind checking the below mentioned details and performing the steps to check if it helps?

1. Go to Preferences > Performance and increase the Camera Raw Cache size to 10.0GB or more.
2. On the same tab, check the option to Use Smart Previews instead of Original for image editing and uncheck the option to Generate Previews in Parallel.
3. On the Performance tab itself, select off from the drop down for Use Graphic Processor
4. Go to the General tab and check the box to Replace Embedded previews by standard previews during idle time.

Once you have made the above-mentioned changes, quit and relaunch Lightroom Classic prior to testing the application.

You can also check the steps mentioned in the article linked below.

Nikunj,

thank you for the reply.

None of the aforementioned workarounds (except disabling GPU like I already said in my first message) does an improvement.

With GPU off, the mouse movement while cropping returns to be smooth and quick, with GPU on slow and laggy.

Contrary to matt above, with previous version 8.4.1, I havent't ANY of those issues.

Thanks

Sandro

Thank you. I was having the same problem and this worked for me!

What particular Mouse?

[sandroriz]

I use a Logitech MX Anywhere 2 connected with bluetooth (logitech Options software 013.010.00003)

I tried with the touchpad of the notebook and with another Dell wirelles mouse (in both configuration, bluetooth and usb keys) and the lag remain if Gpu is Custom or Auto.

Logitech Options. That plug-in just screams Agggghh...

Unless you use special keys on the mouse mapped for LRC or a keyboard with that knob, the plug-in has no value. Not needed to just use the mouse normally.

Known bit of buggy software, no mater how many times they update it. That one plug-in might be your problem. Disable it, Re-enable your GPU  acceleration (for now) then relaunch LRC. And see if things improve.

No gaurentees

Thanks David,

I tried your suggestion, but unfortunately it is not the cause of the issue.

With GPU off the difference of smoothness and absence of lag is still evident respect to GPU On

It is not the first time that I have to downgrade (eg. first version of PS 20, quite unusable!), but this time the format of catalog is changed, so I would loose all the work I've done in these days 😞

[GoldingD]

And as your on Windows OS, What GPU was that again? And what GPU driver version?

(this would be useless for a MAC OS, as you are at Apples mercy as to GPU driver version updates)

[PrinceMike]

I'm seeing the same exact thing Sandro.  Dissapointing given that I just built a new machine and am using a Nvidia RTX 2070 Super, a current generation card.

Here the solution for the Crop Issue (not for other slowness)

https://feedback.photoshop.com/photoshop_family/topics/crop-function-unusable
(basically on win10 create a file config.lua with this line and put in the appdata preset folder

C:\Users\<username>\AppData\Roaming\Adobe\Lightroom)
Develop.enablePostCropVignetteEffectDuringCrop = false

Did not work for me!

I upgraded my Lightroom to the latest version and was shocked to discover that the crop tool does not update the image on my second monitor unless I jiggle the crop around but even then it lags bt several seconds! If I switch to Live view the crop works in real time but you cant really edit in Live View! I have an Nvidia GTX 1050ti with laatest drivers. I cant find any solutions yet to this issue that worked so I reverted to the previous version of Lightroom which meant using backed up versions of my catalogues as version9 changes the catolgues and they become unusable for previous versions! Fortunately I had back ups otherwise I would have lost everything! Thanks Adobe!

I resolved also the second issue (slow drawing the lines of the Upright Guided command) stopping a service called Acronis Active Protection. Stop it and set startup to Manual or Disabled

[nathanr57706027]

Just had the same issue. Disabled Acronis Active Protection (as suggested above) and I return to getting acceptable (not brilliant) performance. Thanks for the tip - would never have guessed that an unwanted service bundled to my backup tool would cause cropping in Lightroom to be slow.

[kennethh38950740]

Yup, having the same issues and this worked for me.  I have a heavily over-clocked 4770k, 32GB of RAM, GeForce 2080, and running off a fast SSD.  In other words, plenty of hardware.  Canon 5D4 images (30MP RAW files).

So...is than an Adobe issue or an Acronis issue?  Any resolution to fixing this AND being able to use Acronis?  Out of curiosity what is the root cause (why would these two things conflict with each other)?

Thanks!

[JaimeGM]

Oh.

My.

God.

Thanks a lot.

I had the same issue. I jut can't believe you found the acronis thing and fixed it.  How did you track the bug back to Acronis?

[pasternaklovesyou]

Thnaks a lot! 

"Config.lua" works on Lightroom v.12!
