Lightroom CC brush hyper slow

Report · Apr 25, 2015

Just installed the new Lightroom CC and OMG the brush is HYPER slow... like almost unusable with the GPU enabled. Like 20 times slower, no kidding. And my machine is pretty fast and the GPU pass and is compatible and pretty fast with anything else.. Slow like I do not see the results until I release the pen.... Same Machine, same photo LR 5.7 works perfectly fine.

So does anyone know what's causing this issue exactly? Where is the bottleneck? When I'm experiencing this "lagging" issue with an adjustment or healing brush I'm not seeing any excessive spikes in terms of CPU, memory or HDD resources on my Mac Pro. So what is the source of the slowdown?

Report · Jul 31, 2015

No efficient code or programming I guess.... The latest version released a week ago if you turn OFF GPU will behave like 5.7.1 but still be super slow with GPU enabled.

Same issue with the adjustment brush and overall slow performance with LR in general. I'm a professional photographer. I average 80,000 photos in each catalog. I spend 8 - 10 hours in LR daily. I recently built a computer with LR performance in mind to try an combat the over slowness, stutters and delays. The upgrade had has next to no effect. LR's general performance is still painful, however the adjustment brush issue is straight maddening. Off topic: Tethered Capture (Nikon D700 to USB 3.0) is so slow that it serves absolutely no purpose and can't even kind of be considered for use around clients.

Your only solution as I see it is either some of the Adobe gurus tell you on which hardware they tested this before consider it ready to release, and get that, or you go back to LR 5.7.1.

If you do a lot of brushing and/or spot healing, the Lightroom Develop Module (and sometimes the Library module) is going to be slow. Turning on the Graphics acceleration in Lightroom CC/Lightroom 6 will make this problem worse. And I seriously doubt that Lightroom 5.7.1 will be much better if the brushing is the cause of your slowness.

You might want to try using Photoshop or Photoshop Elements for your brushing and spot healing. This will result in the rest of the tasks in Lightroom speeding up considerably.

If you still think you want to brush in Lightroom, do not do any lens corrections until you have finished brushing.

It would also help to get the fastest CPU you can afford ... and by the way is that a typo, your memory runs at 666MHz? That's kind of slow by today's standards.

Look. I'm using this on a brand new HP Z840 with dual 10 core Xeons, 128 GB or ram, 1200MB/s SDD and a Quadro 6000M and LR7 SUCKS. There is no faster machine than this on the market at this point neither faster GPU. LR7 should never released in the current state.

Using Photoshop is not a solution for the people that edit 100s of photos per day, it's slow and once you open a CR2 or a DNG and save it as a TIFF 16 bits to keep the quality from PS it becomes a 400MB file easily. That's simply not possible as a workflow.

Yes, LR7 sucks because it hasn't been released , you're working with unfinished software.

Seriously, if it isn't working for you, it isn't working, but it does work for many people. I don't know what's different in your case.

LR 6 or CC2015. Sorry. It probably works for people doing small things. Everyone that complains in here have problems when doing extensive use of its tools.

Some people are not complaining, and at least one says LR CC is faster with his setup than LR 5 ever was.

Report · Oct 02, 2015

Probably not using brushes or many graduated filters. Good for that person. Again. Adobe should specify what hardware to get to use their software. Because believe me, were I work we have all kind of machines, and have yet to find one where it works acceptably

You seem to be discussing two or three different problems as if they were one problem, and I'm not really sure which one you are discussing (or maybe you are discsussing all of them).

Brushing and spot healing causes Lightroom to slow down to (sometimes) unusable levels, this has been a problem ever since I started using Lightroom at version 2.3; and is unrelated to the next 2 problems
Lightroom 6/Lightroom CC is slow with the graphics acceleration turned on, and so the advice is to turn off the graphics acceleration.
Lightroom on some very capable machines is slow

1 - I can use heavy. And really heavy brush in LR 5.7.1. Talking about well over 100 strokes. With almost no delay on 50MP images. LR6 gets super slow with and without GPU acceleration after the first 10 or so strokes.

2. Even with GPU off is slower than LR 5.7.1. With GPU on is just unusable.

3. It should not. Shows bad coding.

I just noticed the same thing here using LR CC and one of the supposedly 'supported' cards for LR on the Mac.

Graphics Processor Info:

ATI Radeon HD 5770 OpenGL Engine

Check OpenGL support: Passed

Vendor: ATI Technologies Inc.

Version: 4.1 ATI-1.32.25

Renderer: ATI Radeon HD 5770 OpenGL Engine

Not sure what's going on but I haven't noticed this prior to the most recent version of LR CC. Turning off graphics acceleration (deceleration?) and the problem instantly goes away. Glad I have lots of CPU cores on my mac.

It is pretty weird. I think they have tons of optimization to do and may be not all the experience. May be they need to hire people that knows about this. It used to work extremely bad in my computer and since the last version is working pretty well. I hope next version does not break it again.

I have the latest iMac 5k. Yes turning off graphic acceleration helps speed up brushes but then other adjustment tools like Exposure, contrast, shadows and highlights start to lag. Just can't win.

Anyone knows if Adobe is working for a solution for this? Or are they too busy designing new features that nobody wants and removing them?

I really wish they give priority to basic performance issues like this, instead of focusing on new features.

I just upgraded to an AMD Radeon HD 7950 3072 MB. And I tried turning graphics acceleration back on. While it was a little bit better, there was still lag and I turned it back off.

Now THAT is interesting.. I don't have that behavior with either the new graphics adapter OR the old one.

I'm still experiencing problems with LR 6.3 with brushing and GPU Acceleration on. While working with GPU disabled, it keeps crashing. With GPU enabled, it is hyper slow and not workable either way. No response yet from any Adobe engineer / employee that this is being addressed by engineers.

Bought C1 Pro already, but I keep hoping Adobe will fix this issue. Any thoughts here?

note: I proces more than 25GB in a week on raw image files only.

Hi All

The only thing that eliminate the slowness was to upgrade my desk top system, upgrade to a larger internal RAM from 1X4G to 12G (1X4G + 1X8G) .

this after open the TASK-MANGER (Window) and realize that LR took 90% of the RAM ussage (now its ~30-40%).

Now I can work fast, meaning that mostly the machine wait for me than opposite 🙂

Yuval.

Good for you, although 4GB is really low for these days, and most of us have this problem even with machines with 128 GB or RAM like my HP Z840….. but the latest versions of LR has gotten much better, still not as fast as the last iteration of 5.x …

Report · Dec 21, 2015

The problem did not exist with earlier versions of Lightroom and is related to the way LR uses the video card's graphics processor. The slowness problem is solved by unchecking "Use GPU Acceleration" in the preferences menu.

Report · Dec 21, 2015

Even turning it off LR CC 2015 is slower than 5.x with the brushes. It got better. But still slower. Hope they can fix it for good at some point.

Average user might not notice it, but I do heavy retouching with LR and the difference is still big enough to make me keep using 5.7.1

I've got a screaming machine ... 64gb ram, GTX 1080, i7-6850 CPU (overclocked - through I've tested without overclocking) and a set of 3 wicked-fast SSD Pro 950's in a raid 5 config for my data drive and another 960 SSD M2 for the program files... Everything runs ridiculously fast on this machine except LR.

The whole reason I moved to LR years ago was that it was fast... but it's seemingly slowed down throughout the years such that I'm starting to look elsewhere for RAW processing.

Is any solution on the horizon? ... or is this the reason Adobe moved us to 'subscription' model, so they don't have to improve or update their software yet we need to keep paying?

This is just sad because it's been more than 1 year that I purchased the fastest imac 5k available with fastest video card and maxed out memory but the brush performance of LR6 is worse than my retina Macbook Pro from 2012.

Adobe Inc. and the Eric team have made me lose any confidence left in them. Perhaps time to start looking for other raw editors out there for the switch.

this is a joke solutiotion, isn't it the keyfeature GPU support?!?

I am also having this problem. I have updated my operating system, my graphics card drivers, my software for my Wacom tablet, and my Lightroom. I and a lot of people are still having this problem.

Where is Adobe support?

Why has this post been up for so long and no one from Adobe taken notice?

Why have I paid so much for programs that won't do what is advertised?
