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

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.

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!

System: Windows 8.1, 16gb Ram, Geforce GTX 970, i7-4770k

this version of PS DO NOT release memory after closed a file. any fix?

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.

I've had this issue since Windows 10 came out and even disabling the rulers doesn't work :/ I wish the issues are soon fixed..

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."

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!
