Question

Photoshop CC 2018 (and 2019) extremely slow

Hey guys,

I have a 2017 27" iMac, specs:

4.2 GHz Intel Core i7

40 GB 2400 MHz DDR4 RAM

Radeon Pro 580 8 GB Graphics

This machine shouldn't break a sweat with Photoshop, however Photoshop is performing the worst I've ever encountered this example is only a 350mb Photoshop file, with about 56 layers (most flattened with a mask) in 20 groups and 5200x3500px.


• When using a brush or eraser tool, it lags so much that it takes nearly a minute to complete the stroke – then doesn't even follow the stroke I made!

• Zooming in nearly crashes the file.

• After about 5 mins of trying, PS just stalls and wont do anything. Open Force Quit Apps and it doesn;t show PS as not responding either.

I've tried using it with the 'Use Graphics Processor' unticked and it runs even worse!

30gb of RAM alocated to PS.

Using default History & Cache

Scratch disk has 1.2tb spare

I never use flick panning or scrubby zoom, or any of those kind of features.

Would this benefit if I got an external SSD to use as a scratch disk?

What is going on here?

      I just checked Photo Paint 2018 from Corel - the same PSD file - amazing what the difference in speed! Rather, I will stop prolonging the subscription of adobe, they totally stretch us, offer worse and worse products, focusing on some miracles, probably only for bloggers. Failure, after all these years.

      I’m glad to know I’m not the only one... brand new imac and can only edit efficiently 4

      photoshop images at a time. This has wasted way more of my limited time than I care to admit! Downgrading to cc 2017 asap!

      ...and I thought it was my iMac....NOPE!
      For the very first time in the last 28 years since I've been using Photoshop, this is where I question the company to its performance.  I finally upgraded to the latest version.  It takes more time for the software to open than when I turn on my computer.  I'm also disappointed with the Transform feature...what a mess!  I'm going back to the earlier version since I don't want to be late with any work I have to do for my clients, capice?

        Same issue here with latest Oct 2018 update. Couldn't even save a simple png without it taking 20 minutes...

        Switched back to CC 2017.

        No problems.

        Wish Adobe tested out any bugs before launching updates... smh.

        Same problem for me. Upgraded to CC2019 a couple of days ago on my iMac and I've spent more time watching 'Type Rendering' progress bars and spinning beachballs than I care to mention. I am uninstalling and reinstalling 2017 now. There's no point using flashy, new updates if I can't work efficiently. What a waste of time. There should be a minimum performance warning every time they release a major update. And thanks for removing all my workspace preferences across the suite so I have to rebuild them from scratch, yet again.

          Agreed.

          Downgrading immediately. This new update, what I assume is a Beta version, is horrible.
          Using transform with rulers on basically every image. With the new version that´s not possible anymore, unless there is a workaround that I´m not aware of. Without this functionality I can´t deliver the quality that´s expected.

          BTW, are most of u guys mac users? It seems Adobe almost stopped updating and support for mac users. Windows users have a lot more funcionalty in their versions. Sitting in an office with both systems. Very annoying.

          What seriously?  I would have thought Mac users were Photoshop's key audience.  Using a 5 yr old iMac with a brand new SSD and PS is struggling to open a 30MB file.  

          Been thinking about upgrading my computer lately and seriously reconsidering the whole "Mac is Great for design" crap.  At their current prices, starting to think a custom PC might be a better approach, especially is Adobe suite isn't cooperating.

          I called Adobe Support and found a solution. My main performance issue with using the Adjustment Brush. When I would tap the brush, I would get a 6-8 second spinning beach ball. Then applying the brush across my image would take another 10 seconds for the change to visually take effect.

          So, the Adobe support gave me these steps and it worked for me.

          1) Go to Preferences and then Performance tab.

          2) Uncheck the "Use Graphics Processor" check box.

          3) Click the "Purge Cache" button.

          Not sure if this would work for others, but apparently my top-of-the-line 5K iMac may need a graphics driver update as the new Lightroom CC Classic 2018 doesn't seem to work with it. The support person did say to frequently purge the cache since it will build up over time and be the most likely culprit to slower performance when you are working in long sittings.

          My next step is to contact Apple to see if there's a graphics processor driver update, but I don't have high hopes for things working well between these two vendors.

          I hope this helps others!

              I'm sure it's an issue with Kaspersky not PS.

              Not sure if this helps anyone...

              I'm using CC2017 on a WIN10 platform. For other reasons I have had to switch off my anti-virus (Kaspersky) when using PS, this immediately caused it to run very, very slowly. I followed the recommended process of checking Plug-Ins, I only had the Script Listener, when I removed it PS ran as normal. It runs fine with the AV enabled???

              Kaspersky has recently caused me lots of problems where it keeps deleting my own application 'exe' files!

              I'm having similar issues on a 2016 MacBook Pro while editing a relatively small 100MB PSD. 1GB+ PSD's with many layers used to work fine up until recently. I'm now using CC2017 and back to normal on MacOS High Sierra 10.13.5.
