Photoshop CC 2017 Unusable slow

[sarobar_kasaju]

I upgraded my Photoshop to CC 2017 today and since the upgrade it has been very very slow. When I click on File menu the dropdown menu appears like after 3-4 seconds. When I delete layer it take about 10 second. Zoom in and out are terribly slow. I work on Photoshop everyday hope to get the problem resolve as soon as possible.

Is there a way to downgrade to earlier version?

My computer details:

Windows 10 Pro

Processor: Intel i7-5960X

RAM: 32 GB

Graphic: NVIDIA GeForce GTX 780 Ti

SSD

Thanks so much for the thorough reply.  My PC has come to a screeching halt even after a hard reboot.  Boot up takes over a minute, even without PS running.  I had previously moved all photos and document files to my storage HDD and I'll work on other files.  The biggest hog is my Windows/Installer/<files> at 33 GB.  There is a program called PatchCleaner http://www.homedev.com.au/free/patchcleaner​  that will remove all unnecessary .msi/.msp files.  Here is my WinDirStat image:

I hope you can click on it and see the detail.

Getting ready to uninstall Photoshop at this point.

Errr, Right-click C: >> Properties >> Disk Cleanup maybe?

[Terri Stevens]

Munki-boy's suggestion about Disk Cleanup is a good one and a safe option and you should try that. Over 30GB is being used by the 'windows installer patch' It is only a guess, but if you are running the Anniversary Edition of Windows 10 , when it did the update it by default left the original copy of Windows 10 in place to fall back too in the event of the update not working-this can waste enormous amounts of disk space. I can remember removing it myself but don't remember quite how, except there was a warning dialog saying that you cannot then go back to the pre-Anniversary version. It might well have been while using Disk Cleanup as that certainly will remove installer files. Another thing to consider is deleting the 'restore' points as they consume a lot of disk space as well. I tend to leave the .msi files alone on the assumption an installer would delete them if they had no purpose. Remember to run the Windows defrag utility after you do your deleting as the % fragmentation is probably very high at the moment. It will run itself once a week but only while the computer is inactive and so it's an idea to do it yourself.

Two more things to try (one-at-a-time please):

1.  Disable GPU - go to Preferences > Performance and uncheck "Use Graphics Processor" then quit and re-launch PS

2.  Disable Extensions - go to Preferences > Plug-Ins and ensure all the check boxes on that panel are unchecked (turn off Generator, Remote Connections, Allow Extensions to Connect to the Internet, and Load Extension Panels) - then quit and re-launch PS

Do either of these changes help with overall Photoshop performance?

Thanks,

Adam

In addition to Adam's steps, I just wanted to up-level what Naveed reported working for him.

Go to Preferences (Ctrl+K) > Tools: Uncheck "Animated Zoom", "Enable Gestures", "Overscroll" and "Show Tool Tips" .

Does this help anybody else's CC 2017 performance?

Nope.

[JacekPuzio]

Nope again.

This is the first time I have looked at this thread, but I read right through, every post.  Some people have said that Adobe cleared 'a bunch of junk' and that they reinstalled Photoshop.  For other people reinstalling, I have not seen mention of running the Cleaning Tool after uninstalling

Use the Creative Cloud Cleaner Tool to solve installation problems

It seems to me that with a whole lot of people running the CC 2017 update without issues, there might be a commonality between the systems that are having problems.   Working through Jeff Tranberry's Troubleshooting steps might be a useful exercise as it provides a one stop structured approach, as opposed to possibly missing something from Pete's posts here with this now such a big thread.

http://blogs.adobe.com/crawlspace/2012/07/photoshop-basic-troubleshooting-steps-to-fix-most-issues.h...

If it was down to a third party plug-in or extension, then starting Photoshop while holding down the Shift key, would disable those plug-ins for the sake of eliminating them as a cause of trouble.   A lot of Jeff's steps are obviously not going to be relevant, but you'll work it out.

It also occurs to me that while my Windows 10 system is fully usable with CC2017, I have been seeing problems with large projects causing lag, although I am not 100% sure of the timing with this.  I just might install a Previous version to prove or disprove CC2017 as causing my slow down.

Good luck to those people still in trouble.

It might also be worth drawing peoples attention to this

It effectively is a warning about using Photoshop on Sierra and strongly hints at installing CC2017 before upgrading to Sierra from El Capitan and Yosemite. As I understand it CC2017 was not tested on Sierra as they were both in development simultaneously, this could mean that errors can occur when applying Photoshop to the new operating system which won't occur if the program is resident on a system that then is updated to Sierra. I don't know how practical it is to suggest those running Sierra downgrade to El Capitan , install CC2017 and then upgrade again to Sierra, but it sounds a lot of work. This parallel development cycle that Adobe and Apple have is a real nuisance-the same thing happened when CC2015 came out at the same time as El Capitan.

This is a good example of why posters here should say what OS they are using

Not sure if the following helps. I was using Photoshop, Lightroom and Fundy Designer this morning. No real problems for about 2 hours though I wasn't pushing Photoshop. Then Lightroom crashed when I selected a photo. Shortly after, Fundy crashed and then I started to have some weird issues with Photoshop.

I closed all the files within Photoshop so it was just sitting on the recent files screen. However it was still consuming 10GB of memory. I had a feeling memory issues were starting to occur when the crashing started.

I quit and reopened photoshop but it got stuck on the - Photoshop and the CEPHtmlEngine processes were not responding. Eventually, after about 15 to 20 minutes they did respond and photoshop started up. I wasn't working correctly though - weird things like actions not being able to find files. A restart fixed things.

Might be a different problem for people with different 3rd party panels enabled.  You can try Preferences >> Plugins >> uncheck allow to connect to internet and uncheck load panels which makes all the CEPHTMLEngine not load at all.

[Terri Stevens]

It isn't ideal to disable load extension panels as you may purchase an extension in the future and then get confused when it does not work. Instead it's better to close the library panel in Photoshop which will completely kill the cephtml process. Libraries are great but they do impact on the performance of the program.

[munki-boy]

Fair enough if the user is prone to getting confused I suppose

The issue of Sierra was addressed by me earlier in the day, around page 4 OR 5.

Sierra made some major changes that are not easy to overcome and there generally is no turning back. That is why users should always have one or two bootable backups. Before installing a new version, at least one full backup should be made and I don't mean use Time Machine - you can't boot from it, though if you do have an invisible Recovery partition installed (for those who don't know, reboot and hold down the Option key and you can see if you have a recovery partition and what version of the OS is installed), you can restore from Time Machine but it should be confirmed that it is the backup you really want to install.

Many vendors cautioned users about using then-current versions of software with Sierra and some products would attempt to load buy a window would open and advise the program could not be run in Sierra. I have a developer license and started early but did most of my work using a boot partition with Capitan. As soon as OnyX for Sierra was released, I never looked back.

The last major change on this level was when Apple abandoned the PowerPC capabilities with the transition from 10.6.8 to 10.7.  There have been some rough spots through the numbers to 10.10, but Sierra and the lack of extended user maintenance may add to this issue.

If you did have an updated backup, then use a safe program like SuperDuper! (that will allow you to copy back your modified file permissions as well) and do a clean restore.

[Terri Stevens]

For potential Sierra users it is best to load Photoshop under El Capitan and then to upgrade to Sierra-that is the only way you can be certain the Photoshop installer makes all the necessary operating system changes. The alternative is to downgrade to El Capitan from Sierra , then install Photoshop and then upgrade again to Sierra. Just installing on Sierra and hoping for the best is quite risky.

I've given up on 2017 because of the slowdown. Tried all the Mac solutions. Never should have been released.

[sonofmrsnak]

2015.5 reinstalled and the program works fine now.

[munki-boy]

I can't fit a screenshot of task manager here, too many CEPHtmlEngine and AdobeCEF to fit on the screen.

"there might be a commonality between the systems that are having problems."

Yep they have Adobe 2017 installed.

2015 working for most people, 2017 not working for lots of people, same computers, only the software changed.  Please report your hardware profile so we can see what you did wrong with your computer?

I've found that (for me) Photoshop problems arise especially when Illustrator is open as if they were competing for resources. CPU is maxed out and the interface becomes extremely slow (or it freezes completely)

I'm on a Windows 10 machine with 16Gb ram, a couple of ssd (system and data, 200 Gb of free space each) and a Geforce GTX 1060 3Gb

Well this has been fun. Upon uninstalling PS CC and Lightroom, then running CC Cleaner, I rebooted and re-installed. Upon reinstall at one reboot I got the "S.M.A.R.T. Status Bad , Backup and Replace" message which I have learned means that my HDD (Storage) has failed. 

I quit.  I blame Adobe.  I have never had problems with my 2 year old PC until installing this POS software.  NOw I can only hope that Carbonite has done its job.

[Terri Stevens]

Sorry to hear about your drive failure. It is no consolation but  you have just been very unlucky and CC probably did not cause the failure. If a hard disk could be destroyed just by working hard the minimum time before failure, MTF, would be measure in tens of hours rather than hundreds of thousands. Disk Defragmenters and renderers are far more demanding with disk activity at 100% for hours sometimes.

SMART monitors far more than just the platters that make up the disk and it would be interesting to know whether your SMART has picked up on something physical or electronic. SMART for example can detect a failing cable and does thousands of checks on the IDE/SATA controller, it even checks the cache memory on the controller for errors, none of those things are related to activity. A repair shop could test your drive easily, but given the charges they make it's probably cheaper to get a new drive. None the less I'm sorry this has happened to you.

[sarobar_kasaju]

Any solution yet? I was able to downgrade and run 2015 version. Whenever I open 2017 it works fine for few minutes then it starts to freeze and slow down the computer. Here's screenshot of my Task Manager.

[Abhinay7]

Just An idea which works for me....

I don't know will it work for you guys or not.

Goto

Edit>Preferences>Performances and then set the Let Photoshop Use to 50% usage or to be precise 3536 mb

similarly Goto

Edit>Preferences>3D and then set the Let Photoshop Use to let's say 41%

and then restart the photoshop....

I hope it will resolve the lagging issue for you guys as it solved mine....

[SteadfastRacing]

DIdnt work for me.  I tried but thanks for the tip. 

It is EXCRUCIATINGLY slow to try to navigate!  But as soon as you switch to another program, like a web browser all latency disappears and your computer runs normal again.
