Photoshop CC 2015: Unresponsive, laggy, slow, super laggy scrolling via mouse wheel on Windows

Next Problem!

Since our update to Photoshop CC 2015 we are noticing much more problems:

1. Photoshop is really laggy and unresponsive, especially when we are working with bigger files. We are using HP Z820 Workstations with Quaddro 4000, 32GB Ram, Dual Xeon CPU, fast samsung SSD, win 8.1. GFX drivers are up to date and hardware wise there should be no problem.

2. Scrolling via mouse wheel is impossible, because its so laggy that we should have to wait up to 1 minute until Photoshop stops scrolling.

Help would be nice.
Working this way is really frustrating :/

I'm running Photoshop CC 2015.1.2 20160113.r.355 2016/01/13:23:59:59 CL 1059143  x64 (Latest from CC) and my system is:

OS: Windows 10 x64 Pro
CPU: Intel Core i7-6700K
RAM: 32GB DDR4
VGA: nVIDIA GeForce GTX TITAN
SSD: Intel 730 480GB

and I had OP's issue too. I never expected this when I use Photoshop CS6 and CC (the old one).
but somewhat, this is going helpful or not, once I turned off "Use graphics processor" options, I have no single issue.

things that odd is, I have no such problem with lower spec PCs that uses i5 and it's built-in graphic adaptor and AMD Radeon HD7950 graphics card. It's odd. really. because it shouldn't be.

OK, so there is some sort of slowdown caused by your particular video card drivers.
Have you tried updating the drivers from the GPU makers' websites?

Sure I have. My main PC (NVIDIA) already running 364.72, AMD one is 16.4.1 and the Intel one is 15.40. All three PCs running their latest driver.
Maybe, In my opinion, It doesn't appear it is a driver issue or else because I had no problem with old photoshop CS6 which even I turn "Use graphics processor" option on.

Thanks for your advice anyway.

edit:: or maybe it is... on specific hardwares...

Well, nevermind my suggestion. The problem still persists.
I attach a side-by-side comparison "What is the ACTUAL problem" video if you don't understand what is the problem.
Even workspace and UI is unresponsive and all my system is running normal and running top edged software and drivers. Please don't make any suggestion about the drivers.

I'm a PC expert at least. Other applications like 3ds max, Maya, zBrush, Modo, Cinema4D, Corel Painter have no performance issue like Photoshop CC2015 has.

If this problem still persists until the end of this year, I'll stop my annual subscription and bring my old CS6 to use.

You appear to be showing a video driver problem - where the updates are not drawing as they should.  Make sure you have updated your video card drivers from the GPU makers' websites.  There is also a chance it is caused by something else hanging the Photoshop process temporarily - like a third party plugin or a utility program.
Newer versions of Photoshop use more of the GPU, and run into more driver bugs because of it.  And we've seen third party plugins that have bugs with newer versions of Photoshop.

And out of hundreds of test systems, we haven't seen that kind of lag except with known buggy video card drivers (which were fixed ages ago).

... I'm already running their latest driver as I wrote at first comment; 364.72 WHQL which is the LATEST driver. There are no third-party plugins that I use. If that is the system problem why CS6 has no issue?

15.1K Messages

Because Photoshop CC 2015 uses more of the GPU than CS6 did.
Every release we run into new video driver bugs because we are using more of the GPU, then we have to spend a lot of time working with the GPU vendors to get those fixed...

And, again, some third party software can have version specific bugs (usually because they hacked something for an older version and haven't updated).

Did you also ask why your system sees this problem and millions of other systems don't?

But he already said he has the latest driver. Why reiterate the same solution after he's already told you twice? I'm jumping in because I too have this problem. All the drivers are updated. And we're not using third party software. What's the next step?

Because 1) most people don't really have the latest drivers (they got year old drivers from Microsoft) and 2) even current drivers can have bugs.

The next step is to look for other things on your system that could cause a slowdown, either blocking the process, or holding up redraw to reproduce what was shown.

I have no time to depth analysis by attach a debugger to photoshop but I made some rough application analysis. 

Symptoms: Photoshop CC 2015 Unresponsive
Reason: Photoshop CC 2015 bug; Photoshop read entire fonts that installed on a system on each operation.
Fix: Turn off font preview. (type->Font Preview Size-> None)
Analysis: 







This is definitely a bug of photoshop CC 2015 because even font cache is on, Photoshop CS6 has no problem(it's the default setting).
Well, still not fast as photoshop cs6 but after this remedy (ha) somewhat it is going okay.

Oh yeah. And it wasn't a graphic driver issue or hardware or hacked software such.

Hope this is helpful.  
Sincerely.

OK, Photoshop doesn't use that API except indirectly to draw UI strings.
(also, most of those symbols are bogus offsets from only a few known function entries)

My guess then would be that you have a corrupt font or OS font cache.
See  https://helpx.adobe.com/photoshop/kb/troubleshoot-fonts-photoshop-cs5.html

If it was Photoshop font rendering, it would be going down a completely different path, skipping the OS font code.

Chris, "try things that might be slowing the system" is at best vague. If the drivers aren't working for x reason, of course it's something else. What would you suggest? 5C4RxFr0r3 just presented something that anyone can try regardless of their system setup. Those are the sort of things we need to be trying, or be directed to.

Until 5C4RxFr0r3 mentioned this, I didn't even know this could potentially be a solution. Chris, what other options do you have beyond your list? I also just can't believe that even if drivers are up to date, we're simply screwed. I understand drivers can cause issues, but if we have the latest, and PS is still a paperweight, it's unacceptable. Also, "Look for what could be causing slowdowns" is also vague at best. We're here because we can't find what's causing a slowdown or don't have the skills beyond searching through forums. It seems you have indepth knowledge as shown from this last response, so throw us a bone.  If you've seen other systems with "bad fonts" "bad system utilities" etc, then be proactive and provide us a guide here as to how to fix what you've seen so we can try these things. We might not have those identical utilities / systems, but some of us might.

I've mentioned corrupt fonts and OS font caches as a potential problem several times.

Yes, sometimes the current video driver versions introduce new bugs, and you may have to roll back the driver or wait for the GPU vendor to issue a fix.  But the latest drivers are usually much better than several year old drivers, and new bugs are rare.

There are millions of possible causes of slowdowns (mostly outside the app), and without some information beyond "my machine is slow" I can't easily narrow down the cause for your specific system.    Showing the problem (screen recording) helps, because that can narrow the possible causes to a much smaller set.   Getting a profile of the app in the slow state helps even more, but most users don't know how to do that.  Even describing the problem in more detail can help narrow the possible causes.

I don't. Would running Sample Process from the activity monitor (Mac) be the way to get that?

Yes, that is the simplest way to get a sampled profile on MacOS.

Can we get a different customer service rep here? Chris, whether or not what you're saying is correct, you're a problem. My jaw opened at a few of your responses. Just about everything you've responded with has been callous and hasn't taken the user on the other end into account. If you're a customer service rep, act like it, or find someone else if you're having that miserable a time. You're just pissing everyone here off and not helping Adobe in the slightest.

I'm just working on a new project in cc2015 with some smart objects and a few hundred layers (mostly small icons and text) And after a few minutes everything is down to a crawl and selecting or moving objects has several seconds delay. Guess I have to go back to CC again. It's not like I'm paying a shitload of money every month to use a 3 year old version - Oh wait... I do!

Systems have a bunch of things going on with them! Don't know what to tell you! LOL! I also will refrain from asking you specifics about your system, or responding to the majority of replies! LOL! I am a Senior Computer Scientist.

Had the same issue on my MacBook Pro with Retina (13") Late 2013 model for so many months. Just tried the hide rulers fix and made it almost as good as Sketch (just the scrolling issue)!

Being a "latest version always" kind of person, I was reluctant but I just went back to Photoshop CC 2014 and started loving my job again. Best thing I ever did. Literally, my hair stopped graying and is growing thicker, my ulcer is healing, my relationship might have a chance and I don't want to kill myself whenever the client asks for changes.

Just go back to 2014 while these people remember how to code while they play with arguably one of the most important pieces of software in computer history.

How what. How to go back a version?

Google "install previous photoshop creative cloud". The instructions will be at the top of the search results.

2016 hasn't been released yet ( maybe this month it will). If you're paying for cretive cloud, you should be able to choose between CC2015, CC2014, CC and CS6

I wonder how much it may be related to Creative Cloud software, the constant checking for licensing and such...more so than a specific application. It wasn't just the big three that were updated so...?

I think it has everything to do with all the problems across the Adobe line. Sure, within the individual applications there are some specific bugs but the much bigger issue is the mandatory infestation of Creative Cloud and its 8-million constantly running processes. The CC software needs to go.

Anyone tried disabling Open CL? Seems to have helped for me. Mind you, helped is key here. It's not fixed or solved anything and if getting one the most basic and universal input methods to work means disabling "features" that we pay for then I really am lost as to what companies are striving for anymore.

I've only just done this yesterday so who knows if it's any better long-term but give it a try.

I'm running PS on a 6 core I7 with 12g of ram and an amd 7750hd 2g video. My two problems were of course "Select and Mask,"  and sluggishness. Well, I can't fix "Select and mask," but found a solution to the sluggishness.

I told my computer to only use 2 cores instead of all six for Photoshop and it worked. I've read where it also helps on quad systems. The only kicker is that you have to set it each time you run PS. For those interested in trying this, It's called "Setting processor affinity."

i must admit i have not been actively following this thread actively for a while (due to my disappointment in Adobe's inaction) so if i am piggy-backing a well known issue, please forgive.  I just wanted to add my input that i am also experiencing the extremely slow Selection when using the Select Wand tool.  

PC, windows 10, tons of processor and memory, video driver up to date

So I changed too many things at the same time to know what actually helped. Not sure if Open CL has anything to do with it, maybe, maybe not, but I have to ask, how do disable your cores of the fly? Is this a Windows thing or third-party software? Interested to hear.

It's a windows thing. However their maybe a utility out there that does it too. Am researching to see if there is a way to make it permanent.

Start PS. Open task manager. click on details. r-click on PS and choose, "set Affinity."
uncheck all processors and then check two processors that you want PS to use and click ok. I chose 1 and 2.

After having worked problem free with a very large 10GB file in ps cc 2015, suddenly everything grinds to a crawl, even after stipping the file away to the bare minumum at 3GB...brush strokes, zooming, switching layers on & off etc.
There was no difference after changing Advanced settings to basic, reducing the cache size etc in the prefs, rulers & type preview also. No change. At this point I updated to ps 2017 ...and then still no change!
However... at this point I start looking at my file. I switched various layers off and then found an increase in speed and fluidity. I then close this file and open another one, a lot larger at 15GB, turn my preferences settings back to Advanced and then see what the differences are. Everything was back to running as smoothly as before! I simply don't understand why, but it seems that certain layers have something going on that corrupts the system.
What I then did was to create a new file of the same dimensions and copy n paste the content of each individual layer into the new file. So far no more problems.
Machine is a pretty new cylindar Mac Pro, dual Fire Pro gfx cards, 64GB of ram, running Sierra etc. Machine performance in itself not an issue.

Sometimes very simple things can slow down PS extremely:
Put a layer that contains layerstyles into a group. On top (outside of that group) put an adjustment layer (in my case curves), which you clip to the group. Zoom in and now try to do whatever you want> PS slows down like crazy to the point that you cannot work anymore! My testfile, although rather large (about 9000x6000px), only has 2 layers and is 3,24MB (yes, 3 point twentyfour) and I have more than 27 GB free RAM and a I7 5930 CPU@4ghz (6-core).

Same issue, WIndows 10 with really good specs. No ruler on, Photoshop updated to the latest version but there's intense lag and it's impossible to work with.

IMHO, I think the problem is not our machines but with the way PS is handling the images we're working on. My PC is an old hp -6 cores@3.2g 12g ram, NVidia 1050/2gvram and a 512g ssd and windows 10 pro. I don' have any issues with speed other than start/shut down of PS.

Stefan, by chance did you look at the efficiency reading when PS slows down!

Right now Photoshop CS 6, Illustrator CC 2015 and Firefox browser (5 tab open) are running simultaneously on my computer. I can't see any lagging. And my system is core 2, 6320, 1.86 ghz. If your operating system is Windows 10, this could be one reason for Photoshop to run slow. Search 'debloat Windows 10' and try to speed up the operating system. Your Photoshop will be fast.
