Photoshop CC 2015 is so slow it is unusable on my system

This below link helped me out from lagging issue of PS CC 2015

bought Photoshop Just bought a NEW pc very fast hp pavilion power desktop - 580-015xt Installed photoshop

now its slower than my old pc

Hi I just closed the panel. But I am still having lag in Photoshop. I need to check again.

hi thanks

i'm keeping 2014 and 2015

i'm uncertain about 2017 , i don't know if it's worse then 2015

I have two iMacs - one running OS X and the other running - thankfully not upgraded - OS 8 Mountain Lion.

I use CS6 to produce very large image tiles(3GB) usually layered.   When I updated my new 4k Retina iMac to OS 9, CS6 performance ground to a halt and in fact I am no longer able to use it.  Even trying to use a small eraser causes the "busy doing something color wheel" to spin for over 5 minutes at times.  Using my old iMac, same files and moves gives me instant results.  I have read on one forum that Mac changed it's memory paging from OpenGL to one proporietary one called Metal.  Has anyone else heard this? 

I'll never buy another Mac until this issue is fixed...not sure whether the Photoshop group are working on a fix or Apple are...but until it is fixed I'll never buy another Mac. 

I noticed a massive slow down with 2015.5 compared to CS6 (downgraded back to that to test. 2014 was fast too but not as fast as CS6)

I work in the 3d field and have multiple layers in a 4k PSD/PBS's. Above 40 layers. Extreme, but works for this testing.

In my case, I narrowed the lag to the fx layers. If I hide those layers in 2015.5, it performs much faster, but still not nearly as fast as in CS6. In CS6 the file runs fine with all layers visible. I got the best high end hardware (128gb ram, 6950x, 1080Ti...so that's certaily not the issue)

Obviously the code in 2015.5 is not as optimal as in previous versions. I would start with finding the coder responsible for the post fx...narrowed some test to the shadow fx when testing. I noticed there is 2 shadow slots in 2015.5 now so I bet that code got rewritten to the worse. Might be other fx add more to this lag as well.

Overall, this kind of lag seems to be a industry wide problem. Faster machines cause laziness. Programmers cut corners assuming computers will be fine running their small change. There is no longer any restrictions for code size since HD's are larger. Most likely individuals test their code and see their fix works, but once everyone's code get added together, the combination turns it all into snail speed.

Reverting back to CS6 for now. It worked well before and does what it's intended to do for me.

For the missing features, I use other software. There is plenty of competition by now.

In general, the entertainment industry has asked for multiple tools for years without any response from Adobe.

Starting with deluxe paint - mirror brushes...but we need wrap brushes to create seamless textures...clone multiple layers so you don't have to redo your work 4-6 times. Now we got replacements for these from studios like Allegorithmic, The Foundy, Pixologic that are getting closer to replace Photoshop 100%.

As a note to Adobe + Listen to your users 110% if you aim to be at the top.

Hello. I've been searching for a fix of Adobe programs lagging for quite some time now. I even opened a new thread, as I have some observations to share that might help someone with some input in how things work - to understand what happens and, maybe figure out a solution. I saw here a lot of people with a lot of problems with software, but it seems there are many different ones (problems), so this thread became very cluttered ... But I will share my observation here too, hoping for the best

So, to try to cut this short: I am using Adobe Photoshop, Illustrator and Lightroom cc 2017 now. My machine is way over Adobe suggestions, even way over my real needs, so, problems are definitely not from a machine. I am using Windows 10 as of 6 days ago (was long-time windows 7 user, skipped 8 ...)

First time I noticed a problem is after Illustrator cc 2015 update. So, original Illy 2015 (one with orange/purple splash screen girl illustration) was OK! After that one, Illy started lagging, after 10-15 minutes of working. so, I rolled back to the one that was OK, and stopped updating. Same thing happened with Lightroom cc (6.6) update.

Now, I installed windows 10 and all CC 2017's, and the lagging is here again. When Illustrator starts behaving poorly, everything else start going bad. Photoshop, windows, everything. Solution is to turn off programs and start them again and then I have 10-15 minutes of good times
I tried everything I've found on this thread *(and others, but this thread actually HAVE IT ALL ). Nothing helped.

Here are my observations I didn't find here:

• When the lagging starts, it is on for things like showing menus, moving mouse over anything clickable ..
  Trying to, for example, put up layer properties is a nightmare, it takes at least 5 seconds (though, I saw much worse cases on this thread) ...  But the program itself is working fine (so it is - making it start to work that takes time). I have a PS test to check for speed: new 300x400mm document, press D for resetting colors, add noise - uniform, monochromatic, maximum setting, then go radial blur - best quality, maximum setting. PS on my machine does radial blur part for around 24 seconds, when it is behaving ok or when it is lagging, it is the same. But, it takes lot of time and frustration until I press that final OK on radial blur tool, when Photoshop is lagging.
• Photoshop in my case do not start lagging unless I am working in Illustrator. For this I am not completely sure, since I often need Illy in my work, but so far - PS never lagged on it's on.
• Here is the one from tonight: When illustrator started behaving bad, I noticed that whenever I put mouse arrow on top of something clickable (menu, file name on window ...) - blue spinning circle under mouse arrow starts showing up, and it does it exactly every 5 seconds. I also tried on other things: windows start menu, task bar, chrome tab, photoshop buttons ... ... everywhere is the same: every 5 secs circle shows up for a sec and then it is gone for next 4 secs ... Now, it doesn't show on a chrome page, or my desktop, or inside illustrator artboard ... Just if mouse arrow rests on something clickable.
  Then I turned off Illustrator, and the circle is GONE! And Photoshop is behaving good again!

So, it must be that Illustrator is turning something up ... Which brings me to another problem I had with cc14 - Adobe Aftereffects, Audition and Premiere cc 2014 could not open up - they froze when it came to starting up dynamic link library. What caused the freeze was my AVG. AVG addressed that issue and now programs start up. But, can this be something similar?? Maybe Illustrator is using some processes/files in it's work that cause antivirus software to have hard time dealing with it?

Sorry if I am making this old thread still on, but I hope a solution will come soon, as I like new Adobe cc 2017, and don't want to roll back with Illustrator...

I have jut made the leap from 5 to 15, thinking that as I have a sparkling new fast machine it would be a good move.  Not so.  Few real improvements in the program and so so sooooooo...ooo slow.  Why did I fork out the money for this?

I have two PCs: 1) Dell T5500 workstation with dual Xenon 2.4 Ghz processors, 12GB storage, two hard drives, dual monitors running off NVIDIA Quadro NVS 420 adaptors and 2) a Dell Inspiron 15 7000 laptop with Intel HD Graphics 520 display adaptor, Intel i7 2.5 Ghz processor, 12GB memory.  Both are running Windows 10 64 bit operating system and have Adobe Creative Cloud CC installed at latest update levels.

Ever since I went to the CC level of Photoshop, my performance on the workstation (which is where I do my Photoshop work) has become miserably slow.  I was fine on the CS6 level.  For example, if I use the magic wand tool, after about the 3rd or 4th click (in add mode), I can go make a cup of coffee while waiting on PS to give me back control on the workstation.  On the laptop, I see NO performance problems using the tool.  It has reached the point that if I want to do any selection work I have to send the file to the laptop and do it there then send it back to my work station. 

I have been following this thread for sometime and trying all of the suggestions.  Nothing has resolved the problem.  How do I go back to the CS6 level under my Creative Cloud subscription.  At least at that level I could get work done. 

2015 is just a bad release...

Same issues here, late 2015 iMac becomes almost unusable when the anything from the Creative Cloud is opened

Throwing my headache into the ring.

I am having this lag as well, on Windows 10.

• I cannot use my Wacom Cintiq with Photoshop without the software lagging or hanging ALL THE TIME. Using Step Backward never fails to cause this.
• Using Export As just doesn't work at all. Like, I click on it, and nothing happens.
• Takes at least 3 minutes to start up each time, menus unresponsive for a minute or so after software opens

Photoshop never used to be this terrible.

I use a computer that handles Maya just fine, so it's not the computer.
