p.1 #1 · p.1 #1 · LRC: mask curve; removing bright spot next to subject

Hi all. I have two LR Classic questions for which I have not been able to find an answers/solutions.

First, I have noticed different Develop actions that are incredibly slow; especially actions on a mask. The most recent situation was applying a curve to a Subject mask. It has been spinning for about two minutes as a type this (a spinning circle in the bottom right; above the thumbnails and to the left of the Previous and Reset buttons).

I am running on a PC with Windows 10, 64GB of memory, apps on an SSD, images on an HD; LRC 12.5 (I had this problem on my previous version too - 12.2). I have the Performance tab open in the Task Manager and immediately pop over to it when I have one of these "experiences". I can see that I am only using 22GB of the 64GB memory, about 35%-40% CPU (after a VERY brief initial spike to 52%) and 30%-35% GPU. The image is actually OOF while this spinning circle is present. I just clicked on the previous step in history and the sharp image returned immediately. I tried it again and CPU is at about 25% and GPU about 20%. It again ran for minutes without returning but immediately responded when I cliced the previous step in history.

The Mask Curve future is completely unusable like this. While this is the worst example I have encountered, more common occurrences are with moving source bubbles around when using one of the healing features. I often wait 3-5 seconds for the move to come into effect.

Does anybody have any idea what is going on? Do I need to turn on/off or otherwise modify some setting?

The second question is around removing a bright spot that touches a subject. My current example is an opening in the b/g vegetation that is causing a bright spot immediately next to the bird's head (touching it). Luminosity mask doesn't work because that area of the image goes grey if I pull down exposure, White and or Highlights to the degree needed. If I use one of the healing features it creates a dark area immediately next to the bird (the bird's head is black where it meets this bright spot and is pulling some of its source from this). The further away I move the target bubble, the less noticeable this bright spot becomes but then I end up creating a halo line next to the bird.

Thoughts/suggestions? There must be a better way to do this!

Please feel free to answer one or both.

Thanks!

For the 2nd issue I would move the image into PS and use the remove tool. It does a great job recognizing and preserving the edge of a subject when you need to remove something adjacent.

If you want to take the image in as a Smart Object you can still use the Remove tool, just create a blank layer above the image, verify Sample All Layers is checked.

The edit (remove) will change if you make changes to your Smart Object layer (eg change an exposure) so make the Remove edits when all your PP is done, then flatten the layers.

I had never used the curve in masks so I tried to replicate the problem you described. Used an image of a flower, used Select Object (is that what you meant by Subject?). I selected the flower using Rectangle Select then moved the curve pretty hard. The flower changed almost immediately ... no delay. I added a couple of other global edits and they were fast as well.

I'm also using a Win 10 PC. I upgraded my GPU recently to an RTX 3060. The CPU is an older i7 7800. Also 64GB RAM and C/caches on separate NVME drives, images on a SATA SSD.

What CPU and GPU are you using?

One other thought is to make sure you have the GPU enabled. I'm sure you do but I've been able to make LRC crash when running Denoise on many files (over 100). When it does this it turns off my GPU and I can't turn it back on (it's greyed out). I have to close and re-open LR and re-enable the GPU.

You could also see if there is a new driver for your GPU (check the maker's website, MS won't find one).

mcbroomf, thanks for the replies.

My CPU is Intel Core i7-8700K CPU @ 3.70GHz 3.70 GHz

From what I can gather, GPU 0 is integrated on the motherboard (Intel UHD Graphics 630) while GPU 1 is on the video card (NVIDIA GeForce GTX 1050 (non ti)). The video card driver is 31.0.15.3623, which I find confusing because when I check to see what the most current driver is, the NVIDIA site says 536.99 (released August 8,2023). That's quite a difference in numbers. The 536.99 is for the Studio driver, which I would think is what I want rather than the Game Ready driver. But even the Game Ready driver has a similar version number (537.13) so 31.0.15 seems like it is a number for something else, even though this is the driver version specified in the properties window and my drivers were update less than a year ago.

Here is what NVIDIA says about Studio and Game Ready drivers:

Game Ready Drivers provide the best possible gaming experience for all major games. NVIDIA's driver team exhaustively tests games from early access through release of each DLC to optimize for performance, stability, and functionality. These drivers are certified by Microsoft’s Windows Hardware Quality Labs (WHQL).

Studio Drivers provide the best possible experience for key creative applications. NVIDIA does extensive testing across the top creative applications to ensure the highest levels of performance, stability, and functionality. These drivers are certified by Microsoft’s Windows Hardware Quality Labs (WHQL).

Thoughts about the weird video card driver version numbers? Am I correct in thinking that if I do an update of the driver, I want the Studio driver (it sure seams like it)? Anything to leary/careful of in updating the video card driver?

In LRC, Preferences -> Performance, in the Camera Raw section, Use Graphics Processor is set to Auto. It has the details of the video card, including indicating it is 2GB. It further states "Your system automatically supports limited acceleration." Further down is Video Cache Settings. It is set to limit the video cache size, with a max size of 3.0GB. Clicking the System Info button back up in the Camera Raw section show:

Dedicated GPU Memory Used by Lightroom is 2655MB / 1976MB (132%).

I am not sure how my limit came to be 3.0GB on a 2GB card. I am thinking I should be setting the limit down to 2.0GB, but I suspect I would need to purge the video cache first (or it is down as a part of making the max cache smaller?). From what I have read this will result in reduced performance in the short term as it works to rebuild its cache contents. Any thoughts on if/how I should proceed with the video cache max setting and purge option?

Thanks

Download the latest studio driver from nVidia. The installer will identify your card and install the correct driver. I suggest not installing anything else they offer.
Unfortunately, that's an old card (a year older than your CPU) with only 2GB of VRAM and was low end even at the time. A better graphics card would probably make a difference and you could use it in a new build also. An 8700K and 64GB of RAM is still viable.

I agree with EBH. My system has a CPU that is a generation behind yours and with a new GPU it runs pretty well, including having no issues with the curve/mask you described. Sorry, I have no experience with a GPU with low memory, but I don't think the video cache impacts stills editing.

I updated my old Quattro GPU as well as the RTX 3060 I have now several times with no issues.

On the 2nd issue, the Remove tool can take a little time to run, but give it a try. I think it may be time for a new GPU though. Just check that your PSU can handle whatever you choose. You will probably need a power cable.

Thanks for the reply EBH. A new, better card is certainly tempting, especially so if it could be used in a new build in a few years. Do you have any recommendations for a video card that would be optimal/near optimal for LRC?

Having said that, I prefer to understand the strange performance issues I am experience but mcbroomf is not on a similar system. It may be that if these problems are identified and resolved my current configuration, video card included, is suitable for me for the next few years and I will build out a complete system at that time.

I had an older GPU than yours, a Quattro P2000 with 6GB I think. It gave me pretty erratic results with Adobe's new (at the time) Denoise. Initially it failed. After a driver update it ran (several minutes/file) but only 2 or 3 times before failing. I could sometime get it to run again after purging the cache, sometimes not and I'd have to restart LR, sometimes the whole PC. I guess my point is that it's possible you won't be able to find the root cause.

For the second issue, if the surrounding area is not complex, you can use the clone tool in “darken” mode to clone the nearby area into the bright spot.

Thanks for the post dpm321. Is this "darken mode" that you talk of a PS thing or also LRC?

As others have pointed out, your weak link is your GPU. However, before you just buy a new one, you'll need to know the wattage of your power supply in your PC, as most of the newer GPUs are going to require quite a bit of power to run, and will require extra cables from the power supply to provide that power. At a minimum you'll probably need a 500W power supply and ideally 750 or 1000W; some of the newer GPUs will use 300+ watts on their own.

If you want to buy something now that can last a long while and be used in a newer PC going forward, I'd suggest the Nvidia RTX 4070 Ti. It will use less power than most of the previous 30x0 generation, has a good amount of VRAM and lots of tensor cores, which are key to all of the new AI-based tools like masking, DeNoise, etc.

jhapeman, the Nvidia RTX 4070 Ti is a very impressive card indeed. The only thing more impressive is the price - $1000CDN to $1300CDN! Any chance you know the winning lottery numbers and are willing to share?

The 4070Ti is a good upper-midrange card, but the 4080 and 4090 are more powwerful.
I use the 4070Ti since it is available in a form factor (3 slots) that does not overwhelm the interior of the computer and block the PCIe slots like the 4080 and 4090. The power draw of up to 285W is also about the most I want to have in a box with a CPU that draws >225W. I have several Corsair RM...x PSUs and there is a new cable available that avoids that Mickey Mouse Y adapter you get with the newer graphics cards. If you buy a new PSU they may be including a 16-pin (12+4) cable.

I can bulk process 61MP ARW files with DXO in Deep Prime mode in 2.0 sec. each. That's good enough for now, but I'm sure the softwares will get more painful and require more processing as time goes on. The RTX 40 series will have support in Win 10, 11, and 12 at least so you can conceivably use it for a good long time. Eventually the VRAM will be a limitation.

Right now I am running LRC Denoise on an image. It says it will take about 3 minutes. I have been watching the Task Manager - Performance tab closely. It just doesn't make sense!

CPU: 6%
Memory 19.7GB/64GB
Disk 0 (HDD): 0%
Disk 1 (SSD): 0%
Ethernet (numerous spikes to max): S: 80 R: 320kbps
GPU 0 (Intel(R) UHD Graphics 630): 5%
GPU 1 (NVIDIA GeForce GTX 1050): 1%

Clicking on Ethernet, it makes reference to our Internet provider for the DNS name.

If I knew absolutely nothing about what was being done on this computer I would say that its bottleneck is the ethernet, as there is next to no CPU or GPU activity and no disk activity (note: both disks are internal; not SAN or NAS). If the GPUs weren't being used, I would expect the CPU use to be high.

I understand that my video card is hardly state of the art, but I am finding it difficult to say the evidence presently points to the card as the problem. Nothing really seems to be the problem. Other than the fact that it is running like a dog!

Any gurus out there that can shed more light on what these numbers mean and why I am seeing spikes on the ethernet for a self contained system?
