Photoshop CC 2014 is MUCH slower than Photoshop CC in a side-by-side comparison.

Have finally discovered how to get my Toshiba P770 Win7x64 laptop with GeForce GT 540m graphics component to successfully run CC 2014 with Wacom tablet.

first, the current NVidia drivers found on the Toshiba support site didn't work for this system with CC 2014.  Apparently Toshiba posts only those drivers they've tested/approved, and after a couple years, these may be significantly outdated.

next: surprisingly, automatically updating the device from the Device Manager did not result in the most current driver -- and in fact, did not work with CC 2014 and the tablet (lagging&strange)

finally, going directly to the NVidia site, Drivers | GeForce, and selecting AUTO DETECT YOUR GPU resulted in the most current driver that WORKED with CC 2014/wacom...significantly faster and haven't experienced any problems with other applications.

additionally, to get 3D happy, after loading the driver(& of course rebooting), made a change to the NVidia Control Panel/Manage 3D settings:  added Photoshop.exe -- HIGH PERFORMANCE NVIDIA processor and made one change to the POWER MANAGEMENT MODE=>NVIDIA driver controlled (although not certain this step is necessary).

At this point, CC 2014 started working well, no lagging, no more slow downs and unexpected behavior.  Pressure Sensitivity with the Wacom pen was back but there was some strange intermittant pen behavior.  After calling Wacom Tech support, found that previous versions of the wacom drivers had left some 'baggage' in systems directories.  after removing a *tablet.dat file, it appears the tablet is now functionally as expected. (ps: noted that even after uninstalling Wacom drivers, not all Wacom Registry keys were removed).

note:  suspect there have been (or are) several issues involved with the problems with CC 2014 on my two Toshiba laptops, which over the years have had several previous versions of PS & wacom drivers installed, a bazzillons windows updates, app installs/uninstalls, and system updates -- noticed that just repeating a reboot several times resulted in different response to how drivers & programs responded.  Probably a clean Win7 install with an updated graphics driver would have made this PS update easier.

I'm glad I'm not the only one. I'm running OS X Mavericks, on a late 2013 Retina Macbook Pro with a Wacom tablet and experiencing the same sluggish performance. I'm using Photoshop for web design using many layers and documents typically around 1920 by +1000 pixels, and around 100-200mb. Glad Adobe is addressing this issue! Using regular PS CC for now.

Well, experiencing the same issues I have with Photoshop in Illustrator and Indesign. All since the update to CC 2014 and on a brand new Mac Pro (see specs in earlier post). Whats up Adobe doc?

Serious issues, especially when uses custom brushes, I use the Wacom Intuos 5 and I can't draw anymore waiting a few seconds for my lines to appear.

Also overall Photoshop is very slow since the update, deleting layers, opening files, adding fx to text, converting to smart layers... etc etc.

Overall issues:

• Custom brushes, very slow
• Deleting layers
• Editing Smart Objects, superslow
• Handling larger files  (100+MB)
• Clicking certain buttons/menus, have to wait several seconds
• Zooming in and out is incredibly slow
• Overall... everything is much much much slower

What can I do?!

I'm also having nothing but problems since installing Photoshop CC 2014. The previous CC version worked flawlessly for me.

It's extremely slow and unresponsive, even without any documents open, or just an empty document, say 600px x 400px large.

The menus are slow and freeze when hovering or navigating the dropdowns and flyouts, the mouse cursor lags and sometimes freezes and then catches up again. The entire program sometimes freezes and becomes unresponsive for no apparent reason.

I thought it might have something to do with the GPU acceleration so I tried switching that off and restarting with no noticeable improvement. I've double checked to make sure my GPU drivers are up to date.

Keep in mind it was slow and sluggish out of the box before I changed any default settings.

Going to keep following this thread to see if anyone comes up with anything.

To anyone experiencing slowness:  What is your Preferences - Performance - Cache Levels setting?

For anyone who has the problem, could you please check to see if it's reproducible with a new action I've created?  If it is, then we have an easy, repeatable way to a) test to see if the problem exists on a particular system, and b) verify the fix once a solution is found.

Download and run this action on both Photoshop CC 14.x and Photoshop CC (2014) and measure the time it takes to run (to the nearest second is fine).  Watch the little > (play) button to go off to determine when it's done.

If you have been experiencing the CC (2014) slowdown identified in this thread, specifically I want to know if this action faithfully reproduces much slower times to run with the new version vs. the older one.

NOTE:  Select the very first "Soft Round" brush in your presets list before running this action.

I hope they get it fixed even though I don't notice the slowdown your referring to. The only time I see a speed dip is when I load a file from my data drive which is a 1.5 tb hdd. let me try with the file the gentleman above posted. I'm curious.

I understand you're currently looking for Windows issues, but posting my experience here, as the original question was from an OS X Mavericks user.

I'm working in fairly large PSDs, with file sizes of 150MB or more, at mobile device dimensions (like an extended canvas of a screen, e.g. 640x2500, or an iPad Retina display at 2048x1536), with hundreds of layers and dozens of folders. There are many, many text layers. PS CC 2014 will hang on virtually every command. Selecting or hiding/revealing a layer or folder, scrolling across the canvas, an even opening a menu will pause the app on 5 seconds of spinning beach ball. Virtually unusable. The previous version didn't exhibit this issue.

Nothing really tweaked here... behaviors haven't changed since last build. No plug-ins or other background processes. Tried disabling Font Preview Size to no avail. I don't use the Info Panel, Generator isn't running, and I'm not working in 3D. Something clearly went haywire on this build.

Info Palette is not visible and generator is enabled.  I did disable generator from the preferences panel and restart Photoshop, but it doesn't seem to have made a difference.

In experimenting, it appears that the biggest problem occurs when creating a new document.  I tried opening an existing JPG and things seemed to move quite a bit faster.  Not sure if that has to do with turning off Generator or not.
