Lightroom: LR4 very slow under some circumstances with laptop, High resolutions and displayport.

Hello

I'm using Lightroom with a laptop. No Problem in laptop mode (as fast as LR 3.6).
Resolution is 1920x1080

When I use this laptop in its dock, with a Dell U2711 monitor connected via displayport, and a native Resolution of 2600x1440, it becomes very slow (40 Sec to go from libray to develop module, 5-7 sec for loading an image, 3 sec for viewing a preset in left thumbnail window, etc.)

It is not a configuration problem, because Photoshop x64 is working fine, and my configuration is as follows :

Dell Precision M6600
I-7 2860QM
32 Gb Memory
SSD 512GB
Internal Intel HD Graphics 3000 (for laptop screen)
Additionnal Nvidia Quadro 3000M (2BG DDR5) for external display.
Windows Professional 64 bits
LR 4.1 64 bits

I think the probleme comes from High Resolution displays, or display port.

Lightroom cannot be efficient with resolutions higher than 1900x1280, or with Displayport interface.

If someone has same problem, I would be happy then ;-)

Sorry for my english, I am french

We have heard other reports of issues with high res monitors. Out of interest, what happens if you make the window much smaller? Does that help?

It helps a litle bit.

LR is going faster, but not as fast as in a classic resolution on a "classic" monitor (1920x1080).

On the Dell U2711, at full Res (2600x1440), if I use LR4 in full windows, when I clic on thumbnail, it will take 12 secs to load and display the picture an let me start to work.

When I use LR4 on the same monitor, but in windowed mode (half size of screen), it will take 8 seconds to load an image.

After you click on thumbnail, you have a small black popup windows that appears on picture, saying "loading", with a rotating logo.

When I work on the laptop monitor (full res at 1900x1080), I do not even have that popup, because image is loaded instantly when I clic on a thumbnail at the bottom.

Absolutly no problem with Photoshop CS6 64bits. Only Lightroom 64bits has this problem.

And I mostly work with... Lightroom :-(

Have you built large enough previews in advance, either at import or by visiting the Previews menu under the Library menu? You may find you need to choose larger standard preview size in preferences too. That doesn't explain all of your speed issues, but may minimize them.

Hi Benji and Victoria,

I have exactly the same problem.

I'm running LR4.1 on a 2009/ 2010 macBook Pro, i7 2.66 Intel core processor, 8GB 1067 MHz DDR3 RAM, Mac OS X 10.7.4.

Like Ben I almost always use my laptop connected to a Dell u2711 external monitor at full res via the laptops mini display port with an apple mini display port to DVI adapter connected to a standard DVI cable.

Editing is painfully slow and unresponsive. Almost exactly the delays you have described with slider response, loading of images (even when 1:1 previews are available).

Btw Victoria, I always build 1:1 previews on import.

When using my laptop on it's own with the built in screen 1680x1050 none of these probelms occur, or at least not at any significant level.

It's a huge problem for me (I'm a professional photographer)... and I'm stuck about what to do.... Is it a problem with the dell monitor? Would a new macbook pro or imac or apple display solve the problem?

I've read so many blog and forum posts about people experiencing the same issues with LR4, but none have mentioned external monitors, and now I wonder if they all exist when using an external monitor (maybe even this particular Dell!)

I'm so keen to get to the bottom of this - any other things I can tell either of you just ask... I can test my setup etc.

Thanks in advance.

Seth, the one thing I'd be particularly interested in is whether you see the same issues with a small LR window on the external monitor? i.e. don't change the screen resolution - just put LR into Windowed mode (not full screen) and drag the corner to make it smaller.

Hi Victoria, thanks so much for the quick reply.

I've just tested, and with a smaller window everything is quicker, maybe not quite as fast as the laptop on it's own, but very nearly at least.

I kept the window the same size as it is on the laptop, and tested by just changing the temp slider, the exposure slider, and testing a few presets.

With a large full screen window the delay between changing the slider and seeing the changes on screen is 3-4 seconds! With the smaller window it's not instant, but close... under 1 sec anyway. When dealing with 2-3000 images some days such a delay is incredibly painful to say the least! And time consuming.

That's very interesting indeed, and fits with some of the other information we've received on larger preview sizes. Thanks for checking that, and at least you know there's a (partial!!) workaround in the meantime.

Thanks Victoria... it IS a workaround of sorts, but introduces other problems to do with working on a small screen!

In your opinion, would this problem be the same with any monitor running at 2560 X 1440 resolution? Or is it specific to this dell?
I have thought about buying a 27" apple monitor or an imac.

Also, I'd be interested to hear your thoughts about this being due to a corrupt preference file as highlighted in the official response to this thread...

As I understand it, it's likely to be more closely related to the amount of data that's having to be processed and pushed to the high resolution monitor. I don't *think* it's Dell specific, as I've heard issues with 30" Apple displays too, but I don't have any solid stats on that.

I'd be surprised if preferences fixed that, but you have nothing to lose in trying it. Just move your preferences file somewhere else, restart LR, and if it doesn't help, you can move your original pref file back again instead of having to reset them all manually.

Same issue here.
External U2711 attached to a 15" mid-2010 2.4Ghz i5 MBP.

I tried with both fullscreen and 1/4 screen window.

Develop mode, advancing one photo at the time. 12MP Raw files, DNG format.
In both cases the loading spiining wheel disappears after 7-8".

Smaller window: image fully rendered in 9-10"
Full window: image rendered in 13-14"

It means more or less 2" from the loading wheel to disappear for the smaller window and 6" for the quadruple size window.
It makes sense.

Hi Paolo, I think you have the same generation Macbook Pro as me.

How is the responsiveness of your sliders in develop module... i.e. when you move a slider how long does it take to see the results?

the time it takes me to switch between photos in dev module doesn't seem to be as bad as yours btw.

Tried with the exposure slider... between 1.5-2.5".

Seems a bit quicker than mine... but then it does vary a bit.

Did you see this thread? http://feedback.photoshop.com/photosh...

Someone suggesting it may be some corrupt preferences file...

Hello all !

It could be interesting to have some technical informations concerning laptops. For example, I have this problem with a Dell Precision M6600. It has an internal Graphic card (Intel HD 3000), which monitors the laptop monitor.
It has an external Card, an Nvidia Quadro 3000M, which monitors external monitors and displayports. The laptop also use the Optimus technology.

Could it be possible that Lightroom has just been optimized for standard desktop graphics card ?

The Quadro Series uses cuda. Is this technology taken in consideration for lightroom improvements ?

This desktop has 2 graphic cards. Could this be a problem under lightroom, when you switch between them ?

If it is a material or a technology problem, then why Adobe Photoshop CS6 Extended 64bits is working perfectly, no matter what graphic cards or monitor used ?

If you could give some informations about the graphic cards you use, and monitor brands and model, it could be interesting.

Sorry again for my poor english ;-)

My mid-2010 MacBook Pro has this:
NVIDIA GeForce GT 330M 512 MB

External monitor: Dell u2711

Same as yours, except for the GPU ram which is only 256 MB.
Processor is 2.4 GHz i5

For me, it's Nvidia Quadro 3000M (2GB DDR5), and a Dell U2711.

So problem with big screens, or with nvidia ? Or display ports ?

I think it's resolution problem, not big screens problem. I had before an asus 26", with max resolution of 1920x1200, and LR4 was working fine on it, as external monitor on the laptop.

Using method concerning corrupted preferences doesn't change anything.
Using 1.1 thumbnails or none doesn't change anything either, but takes so long for generating... I have 1000 Raw pictures per catalog. So no thumbnails for me...

Another problem appears. After testing with big screens, Lightroom keeps staying slow sometimes, even after coming back to laptop screen, as if it was hard for him to come back to initial small resolution. It disappears later, after a few LR4 open/close.

I just hope that Adobe will take all this in consideration, and give real solutions in the next lightroom release.

LR 3.6 is fast, but there is new stuff on LR 4.1, and they are so great that you get used to it.

I'm going to say resolution as my best guess, particularly as it improves in a smaller window. Small preview = less pixels to process. Large preview = more pixels to process = slow downs. I agree that I hope they find a way to speed that up though.

Maybe I have found a solution.

In the Laptop Bios Setup, I deactivated the Intel Speedstep Technology. And then, it seems that lightroom is working much better. About 3 Secs to access a picture.

If you have this option on your desktops, or laptops, can you try to turn off Intel Speedstep option, and make a feedback on this post ?

Thanks a lot...

Yeah me too, I'm mac...
I've read that disabling hyper-threading may also work, but I also can't really work out how to do that...

Disabling a CPU architecture technology should not be the solution.
More likely the problem lies in the source code or, in the worst case, in the way the OS manages the applications at runtime.

"Disabling a CPU architecture technology should not be the solution. " - not a solution, but may offer a useful clue to the engineers to be able to find and fix the issue, and a good workaround for users in the meantime.

It's beginning to feel like Adobe are optimising Lightroom for a non-professional market. A big price drop coupled with the fact that huge numbers of professionals are having problems on high-end systems, with high resolution monitors and multi-core processors causing problems, I think they should release a 'PRO' version... and I for one would happily pay 4x as much for a decent working copy of Lightroom.

They are not.

I'm not suggesting they definitely are, it's just a feeling especially when high resolution monitors and multiple-threading etc (which professionals have as standard and others not so much) are causing problems. It is a possibility and would certainly make some commercial sense for Adobe.

I would imagine it's true that the majority of Lightroom users are not professional, just by their sheer volume. So rather than specifically optimising for a 'non-professional' Adobe are simply optimising for their user base, which is fair enough.

A good example of this is the fact that most professionals I know (including myself) use Photo Mechanic for importing, rating, keywording and various other metadata tasks simply because it is much faster and more powerful than Lightroom for these specific tasks. If Lightroom was really aimed at these professionals then wouldn't Adobe make sure that Lightroom could compete on this level? My guess is that this market is not large enough for this to be a priority for them.

I guess we also have to remember that the problems discussed here (delays and time-lags etc) are simply not problems if you are not a professional... if you are simply importing and editing a few snapshots or personal projects, and you don't have deadlines, then you can live with these issues. When you are processing thousands of images a week with deadlines to meet then these issues become really serious. Hence the issue, relative to the total Lightroom market is likely to be a small one.

Anyway, I'm off topic, but I still stand by my assertion that I'd happily pay for a better functioning 'PRO' version of Lightroom.

Hi everyone,

You'll be pleased to know I have finally found a solution. But it was rather an expensive one...
I gave up with my 2010 MBP (i7, 8gb ram etc) and just purchased a brand new retina MBP: 2.6GHz quad-core Intel Core i7
Turbo Boost up to 3.6GHz
8GB 1600MHz memory
512GB flash storage1
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory

Lightroom 4.1 runs like a dream, even with my dell u2711 external monitor plugged in. My guess is simply that the dual core processor and graphics card on my old computer were simply not up to the job of running Lightroom 4 through a high res monitor. And also maybe the ssd makes a big difference.

My old computer had a 'geekbench' score of about 5500. The new one is 12000... Quite a difference. An expensive solution at 2800 euros, but a solution none the less.

Good luck everyone.

I am running dual Dell30" monitors, 24GB ram, 256GB Samsung SSD for boot and programs, 128GB SSD for Lightroom cache, I7 950 CPU, and lightroom is so slow to respond when moving the sliders. I even re-installed Windows 7 64bit, and light room again on a new drive just to see if that would fix the trouble. Windows rating is 7.5 on this rig. Picture files are stored on 3tb 7200RPM HD.

12megapixel files are not too bad, 22mp are slow and my D800 36MP files are way slow. If I remove several of the modules, there is quite a difference, but the slow speed is still frustrating. I am willing to spend money to upgrade to a speedier CPU (I7 3770) or video card, but I don't want to waste it if will not make a difference.

I have done much searching for a solution but no found so far.

Same problem here, U2711 on a Windows machine, when moving sliders cpu spikes to 100% usage...
