Lightroom Classic CC seems slower than previous Lightroom version it replaced

Lightroom Classic CC seems slower than previous Lightroom version it replaced. To test the performance of the new classic update, I imported some raw pictures taken with a Nikon D810/D850 and am noticing that moving from one image to another (all with 1:1 previews) in the Develop module takes 4 seconds before the image is displayed after pressing an arrow key to move (or using the mouse to select an image). When you move to another image, the UI is repainted first (and, i assume, the histogram calculated, etc.), and then the image is displayed on the screen. Moving between the Library and Develop modules also results in about a 4 second delay before the image is displayed. Moving between pictures in the Library module is almost instantaneous.

This level of performance is unacceptable. Doing a copy/paste of settings from one image to another takes longer in the latest Lightroom than in the previous one as the time needed to display the image seems to slow everything down, thus slowing down the entire workflow process.

Another quick test was to press the right arrow key 10 times in succession in the Develop module to move between images. It took Lightroom Classic CC 20 seconds before the UI finally caught up and displayed the desired image. Doing the same in the Library module takes about 3 seconds.

Or, is this just the level of performance to be expected? Was this not tested during the beta process, or just deemed satisfactory by Adobe?

What's the best way to get feedback directly to Adobe on this?

True!! My version is very slow. Previously version of Lightroom render good...it's slow now.

When I use "Remove Profile Correction", for example, takes 3/4 seconds before redering image. The brush is slow and when I using it heats up the GPU Diode and the fan flies ...

Yes im using a late 2015 iMac and rendering is twice as slow now. Anything with multiple edits is twice as slow as old version. Zooming is twice as slow. Develop module is 1.5 times as slow. Slideshow twice as slow

Like i said there is only 1 improvement while breaking everything else and that is the speed of flicking through photos in "LIBRARY". In develop flicking between photos is painful.

Horrible version. I wonder how we get Adobe to notice this thread? They really do a pathetic job of testing things properly. Talking it up how great their new version is.. LOL what a joke. They have egg on their face.

>The main issue is the rendering engine< They can never fix the rendering engine problem. They try to do a lame work around. When changing pictures there is a 2-3 second delay to render it on iMac 5k. The old version theres a 1-1.5 second delay.

Adobe when will you fix the rendering issue for 5k screens. Worry about 5k screens as that is where the problem is. There is no other problem. Only the rendering engine.

Yes I've noticed Classic is slower on my late 2015 iMac. Particularly when moving the sliders. Previously Lightroom rendered changes instantaneously when adjusting sliders. Now with Classic there is lag :-( On the other hand it absolutely flys on my 2011 MacBook Pro. But I use it mainly on my iMac so I have to say this reduction in performance is disappointing.

I'm also seeing equally slow (actually very slightly slower) performance with the new Lightroom Classic CC. I shoot events, and need to get photos out quickly. When I have an album with a lot of adjustments (crops, exposure tweaks, brush/filter adjustments, sharpening/noise changes, lens corrections, etc.), it's just painfully slow to do anything - get a crop frame to appear, use the "alt" key to see clipping, etc., etc. 3-5+ seconds there and still taking 5+ seconds to render when I move to the next image.

I have a fast i7-based machine with SSD's and plenty of RAM. I've tried all the performance tweaks before (and still have those set as my default options). I'm not going to keep chasing this rainbow. All I can say is using ANY other competitive product is at least 3x faster (total time to produce a finished album), without the need for a single tweak. With those, I move quickly between pictures, and adjustments are near-instantaneous. IMO, it's definitely some sort of memory issue (and yes, I have graphics processor acceleration off, have a huge cache specified (on an SSD), 1:1 previews, etc.). I've been using this new version since yesterday and it gets progressively worse the more work I do, just like the old version. It "rebounds" a little (but only for a little while) when I restart the program, but I can't afford to be doing that every 5-10 minutes.

This version is not an improvement for me at all. Same exact problem(s)! Did they even beta test this on machines that were showing the problems before??

of course they didn't test it, and of course they have no clue about anything. They are complete morons.

Dont forget they have been telling us for the past 2 years they have fixed things but never have.

What a useless smoke screen this release is. I have extensively tested and me and all friends report the same behaviour.

You have fixed scrolling photos in Library view but have broken countless other things making it completely useless. What a pathetic moronic company. I am shocked. I was really excited for this release.

I have just reverted back to 2015 and it is running dog slow but less dog slow.

I doubt any moderator will even read this. Keep in mind i've been testing Adobe products on high end machines for 2 years dealing with engineers at Adobe tirelessly and i know what i am talking about.

Thanks 99jon - except, would that only affect the import performance when building previews?

I know that building previews is supposed to be faster in LR Classic CC, but haven't tested against LR CC 2015.

I'll give it a try at least!

Thanks for the feedback. When you say that "camera previews appear almost instantaneously," is that in the develop module?

I went ahead and reinstalled Lightroom CC 2015 (the previous release) and moving between images in the develop module is almost instantaneous. So, something seems to be broken (or changed) in the new Lightroom Classic CC version...

I don't usually jump along the filmstrip, but just used that as a example to show how the performance degradation can be compounded when doing multiple actions.

For my workflow, I'll import the images and have 1:1 previews generated at time of import (I use a sidecar XMP). After I select the images to work on, I'll edit an image and then either sync or copy/paste settings from one image to another. While Lightroom CC wasn't a speed demon (and seemed to get slower release after release), Lightroom Classic CC seems to pale by comparison.

It also looks like exiting LR Classic CC and restarting it helped a bit as the time has gone down from 4 seconds to 2-3, but still seems slower than LR 2015

I would recommend trying embedded & sidecar from the import dialog – see image below. They appear in the Library with an overlay to indicate they are from the camera. The D850 has large files. They embedded are full resolution jpeg previews as you see on the back of your Nikon.

In the Lightroom preferences, on the performance tab, have you selected this option?

why should he need to select this option when before he didnt need to select this option and Lightroom was faster?

THE ONLY THING that they fixed is scrolling between photos in Library.

Go start zooming in and see how slow render times are. Zoom in then start scrolling in Library mode. Go into develop module and start flicking between photos seeing how long render takes.

They are all slower than the previous lightroom. All i do is use Lightroom for work.

THE NEW VERSION OF LIGHTROOM BROKE MORE THAN IT FIXED!

Upgraded computer to top of the line iMac. Slower than ever. Very upset. Brushes bring the counter spinning icon. Switching images is painfully slow. My time is being wasted. It wasn't that way. I am even considering other options now.

My own experience is that Lr Classic is definitely faster although I have a different workflow. I import using “embedded and sidecar” and then make my picks. The camera previews appear almost instantaneously. After discarding the rejects I generate 1:1 previews for the keepers. I never jump along the filmstrip as these are images I want to spend a little time with editing each.

I have exactly the same slow feeling

I have just updated to the newest version and regret it so much.

Importation literally locks lightroom using only 100% of a multicore CPU even with parallel preview render and GPU enabled.

Application switching to LR takes 4 seconds during importation. Other applications are working perfectly.

Opening any menu (file, edit, ...) takes the same time, accessing LR preferences takes the same time.

Previous versions of LR were far more responsive at import time at least.

Please Adobe developers, fix this dramatic performance issue.

I'll go back to the previous version. This thing is too slow on my computer it has been painfully slow now. Adobe fix this as soon as possible
