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?

Go to your apps and click the arrow to the right of update or install, you will get a drop down menu.

Thank you, it seems to be better! I scribbled the heck out of one of my brushes and it took forever for the lag to catch up.

I just installed Photoshop CC 2018 and I am experiencing extremely slow brush strokes when trying to paint. I have more than adequate computer specs and have tried about a dozen things to try and fix the issue. I am so frustrated! PLEASE FIX THIS ADOBE.

Maybe your video card or its drivers are not compatible with PS. Try turning off Use Graphics Processor in PS / Edit / Prefs / Performance. If that works then turn it back on, but turn off some of the advanced features and see if it sortof works.

If the Graphics Processor is already off, try turning it back on.

Thank you for your reply. Strange, it doesn't seem to make a difference if the graphics processor is on or off.

Adobe, a US$52.99/mo. freak show...

That price would not seem to be the Photography Plan but the full cloud license (including After Effects, Premiere, Indesign etc.).

If you have any particular and sensible complaints please post them on the appropriate Fora.

Takes about 5-8 minutes to just even SAVE an 8 MB file...not to mention blinking cursor that switches back and forth from arrow to hand, etc, lagging brushes and tools, and on and on and on...when will this get fixed!??!??! Some of us use PS for a living and at this rate I can expect my projects to be done next year -_-

I'm having the same problems and I have two dedicated SSD scratch disks that PS is not utilizing for some reason. I get hung up about one minute in and then everything becomes completely unresposive.

same problem with files that ran perfectly fine in the previous version. no added plugins or anything other than the original Photoshop download so please fix this ASAP.

I also just now downloaded the trial version of Affinity Photo. Just to see if my 5000$ Thinkpad wasn't just a computer from the 1990ies.
And yes, Affinity performs instantly.

I just got a bit of a tantrum when just OPENING THE EFFECTS PANEL took as long as BOOTING THIS MACHINE, like 5-6 seconds each time. Making me shout "HEUTE NOCH!!!" which means something like "Even today!"

It was a ridiculous simple job: Just change the colors of some layers and export those versions as PNGs, but it took me half an hour just because of the non-responsiveness of Photoshop. And with each update it seems to get worse and worse.

What is happening all this time?! Are you mining Bitcoins when drawing the UI to catch up for all the custumers that might be leaving because of all the bugs introduced earlier (like not being able to zoom to the mouse cursor and other ultra basic stuff - which now works but jeez have we been waiting for it).

Maybe the UI drawing routines are programmed in Java, being executed by an emulator written in Javascript, running on the Internet Explorer 8 Javascript Engine, then the pixels get saved to a big BMP somewhere on the HD and then loaded back to the screen by another Quick Basic script being emulated by a flash plugin running in a virtual machine.

Oh wait - it can't be, because that way, it would be FASTER than it is now!!

I bet, with thousands of Photoshop users, a whole extra power plant is needed just to provide all the exessive amount of energy needed for these UI drawing routines that should render in some milliseconds but do in a matter of seconds.

I'm done ranting now.
So please Make Photoshop Great Again!
