Photoshop: CS6 very slow and unresponsive on my system

The program is really unresponsive and sluggish to use, menus don't respond quickly, tools do not switch quickly and scrolling a document is very jerky.

I tried setting the tile size to 128k (since I'm doing mostly interface work), setting the graphics processing to minimum and disabled the layer previewes, changed the allowed RAM to 65% and the program is still unresponsive. Also I updated my drivers to the latest version, nochange in responsiveness.

CS5 was lightning fast in it's response, CS6 isn't for some reason.

Is it possible to downgrade only photoshop only CS5? I used the creative cloud service to update all apps to CS6 and I need them, except for Photoshop which I really like to be fast again.

My System:
Win7 64
i7 2600 @ 3,4GHZ
nVidia 570 GT
16GB Ram

So how can I fix the sluggishnes and if it is impossible, can I downgrade Photoshop alone to CS5?

Thank you!

A couple of questions:

Is the app sluggish with all files or just a specific type of file?

Is the app pointing to any older plug-ins (from CS5 or earlier) or do you have any 3rd party plug-ins installed?

Finally, do you have a default set of fonts on your system or have you added fonts?

Thanks,
Adam

That sounds like it could be just an out of date video card driver (bugs in the driver cause slowdowns in drawing). Did you update drivers from Microsoft (mistake) or NVidia?

Could also be corrupt fonts (font preview causing a delay), a bad third party plugin, or something outside of Photoshop.

The App is sluggish with all files, small or big, few or lots (500+) of layers.

I have no third Party Plugins installed, in fact, this PC was bought by my Company especially for Photoshop CS6 because it was running slow on my old system as well.

It is a brand new Machine, a HP Elite 7300 Series MT.

The only non-system Fonts on the machine right now are the ones that come with office 2010 and the Adobe Apps.

The Video driver is the latest version, I used the system tray function with the nvidia tool to check for updates, no newer version is available.

PS PS6 (64 bit) launches, but when I do anything, it hangs. This includes trying to open a file of any kind, as well as choosing Edit Preferences. No dialog or anything - just sits.

This behavior seems to have started after the recent cloud update - I think for Audition (don't quote me).

I'm trying to sleuth out display issues - perhaps a driver. I'm on an HP laptop, 4G ram, huge hard drive, ATI Mobility Radeon HD 5850.

I've also tried launching PS with the ctrl or shft to reset preferences. Any ideas?

I noticed on some old files that the efficiency percentage is low, around 50%.

What are the criteria for an efficient document and how does efficiency influence performance, if at all?

Edit: I Just launched a file with 29% Efficiency which slowly climbed to 100%, sadly no change in responsiveness or performance.

Edit 2: It just dropped to 10%. What the heck?

Edit 3: I just tried to write some words in a single text layer, which took around 10 seconds to update. What can you possibly break so much from one version to the next. Frustrating.

Edit 4: Disabled font preview, no change in performance.

Edit 5: OK I narrowed down the problem to files with lots of layers. When I open a single image the speed is there and the response is immediately, when I open a file with more then a few layers the performance drops dramatically.

Changing the Layer previews, tile size or cache levels does not improve the performance in these big files.

In CS4 we worked on interface files with over 2000 Layers and files over 2GB without these problems.

If efficiency is below 90%, you need more RAM - it means that you're spilling a lot of data to the scratch disk.

You have got to be kidding me. You are telling me that 12GB of Ram for Photoshop alone isn't enough for a 68MB PSD File??

Here is a screenshot: http://i.imgur.com/mEHsz.png

These are the system requirements for photoshop from the adobe website:

Windows
1GB of RAM
1GB of available hard-disk space for installation; additional free space required during installation (cannot install on removable flash storage devices)
1024x768 display (1280x800 recommended) with 16-bit color and 256MB (512MB recommended) of VRAM

I'd say you have a memory leak in your software, otherwise I have no Idea why your data management is so bad in CS6.

That depends on the exact contents of the file. I've got a couple of files that push the limits of the 32G in this machine.

Images take up a lot of memory. That's not a leak, or a bug, that's just a fact. On disk your files are compressed, but in memory they can't benefit from compression.

Again, if efficiency is less than 90% : you're hitting the scratch disk a lot, and need more RAM if you want to keep the performance reasonable. Otherwise you're spending all your time waiting on your disk (which is much slower than RAM). You show 76% efficiency, so your image is 24% spilled out to the scratch disk.

You probably have Photoshop's RAM percentage turned down a bit, or are running 32 bit by mistake.

Photoshops percentage is at 80% (~12gb) and I am not running the 32bit version by mistake.

There are no photos at all in this file, and like I said these performance problems weren't even there with older versions of photoshop.

I get photoshop to run reaaally slow sometimes, and i have 64GB ram installed. Problem is this happens randomly without any visible reason behind it. So i'm confused. 

Also, i've worked for at least 16-18 years with photoshop, so i've even edited images on a Pentium PRO 200Mhz processor, and 32Mb of ram. So making excuses for photoshop to run slugish on a 16Gb machine, is so ridiculous, i can't stop laughing. Not saying it shouldn't with a huge file, but if they could have a version that does 80% of the current version, running on essentially something 4 times less powerful than a modern phone, i would say Adobe needs to get it together, and maybe rethink before implementing 3D features nobody asked for.

i also have been having problems with cs6 , i can't do anything pretty much .If i try to make a new file and a layer or two it starts to lagg, if i add a text layer it gets worst it laggs like crazy ,and it just keeps saying rendering..rendering..rendering for just 2 words ,and it's making me mad not being able to do anything without it lagging like crazy . I may not have the greatest computer but i used to run cs5 on my laptop(same PC using cs6) and it would work flawlessly .

PC: Samsung qx 14"
Intel i5 2410m
nvidia gt520m 512mb
6gb ram
windows 7 64bit

Hello guys..
We have the same problem but more confusing I think..

We got two new machines in our studio, both are MAC 3.55GHrtz, Quad core intel Xeon, 6GB RAM, and both are running mountain lion..

We recently installed CS6 on all machines as we have multiple license usage, and it's running smoothly on all oft them except on one of these two machines!!

We tried everything so far, from reducing the cache tile size back to 128K, to purging All history and clipboard, to allowing up to 85% memory to Photoshop,,etc.
and it's so slow still .. I mean not even opening any of the drop down menus easily..

Any Ideas?
please...

I would suspect a bad font/font cache, or a plug-in on one of the machines.

Here it starts to lag alot whenever a document is open, even a small new document with no layers, here is a video :
http://entity.be/stuff/pscs6_slow_whe...

See the difference when the mouse is hovering over menus how fast the open and close, when no doc is open.
Then with a file open, how they are lagging...horrible to work this way

Awesome! I've been pulling my hair for months trying to fix this. I've re-installed, updated, changed preferences, settings... everything I could think of that made sense. Except the one thing that made the most sense: Windows 7 strikes again. Did I mention how much I hate W7?

I have a the strongest MacBookPro with the strongest CPU available (SSD 512GB + 8 cores 2.8Ghz + 16GB Memory).

the Photoshop CS6 stuck on any operation.
i have also CS4 installed. CS4 do the work without any problems.
Photoshop CS6 is badly slow and i can't work with it anymore.

Again, the slowdowns we know about are caused by external factors.

We don't have your system, so until you tell us more, all I can do is tell you the common causes of slowdowns (which I've done).

Photoshop CS4 was a carbon application, and CS6 is a Cocoa application - so they're calling different OS APIs to start with. Some third party code (like font managers, and some antivirus) needs to be updated with each software release. And then you can always run into problems like corrupt OS caches, disk errors, etc.

Have you tried turning off font previews and relaunching Photoshop?

Question: how can we discover what causing it?
i created new account on the mac and just open file that i know working slow on the CS6 and fast on the CS4.
it run the same in the new user, slow on the CS6.

how can we solve this issue. i just can't work with that software anymore.

Something specific to your system is causing CS6 to act slow - but I don't have your system, so I do not know what is installed, what might have been changed, etc.

I'm telling you the common things to check (since the more common things are the most likely places to find the cause).

Again, have you tried disabling font previews?

Another thing to check is the type engine - have you set to Middle Eastern in preferences? If so, a known bug in MacOS might be causing slowdowns in the type engine. Try changing it off Middle Eastern mode and relaunching Photoshop.

ok. the problem is the Type Engine, as you mention.
with the Middle-East, i am from Israel, it does work slow.
with the other it work fast and the problem not exist.
but we don't have Hebrew support, what i do need for my clients.
what do we do now?

Yep, it's a known MacOS bug -- we call the same routine,but for some reason it is MUCH slower with middle eastern type parameters than with asian or roman type parameters.

We are working around the issue in Photoshop CC, and the latest MacOS release may also help (though Apple is still investigating the slowdown, they think they made it better).

Also, disabling font previews will help the entire app go faster even if you are using the middle eastern composer.

Have the same issues. Ever since the installation of CS6 cloud, the software is very sluggish and non-responsive. One of my biggest annoyances is when I choose a tool preset, Photoshop "initializes type tool." this baffles me completely.

That should only happen once after launch. And yes, I don't know why it happens unless you select the type tool.

Please see the previous posts on this topic about possible causes of slowdowns. Then you'll need to do the same troubleshooting steps to figure out why your system is running slow.

I dunno either. CS5 was fast, Sketchbook pro, Painter, Manga studio pro and Maya are lightning fast. When I upgraded to CS6 cloud, its slow and cumbersome, on multiple machines. Others in the studio complain about he same thing, there is something going on with CS6 for sure.

Please see the previous posts on this topic, and do the same troubleshooting on your system.

So far, the problems have been traced to external/third party causes.

This might help.. because it happened with one of our machines in the studio..

The designer was working on a huge file, and the photoshop CS6 took a auto-backup from this file and from another one as well..
this made the machine to slow down really bad.. after we found these files and deleted them and restart it was refreshed again.. as normal as can be..

hope it helped,

Cheers,
Tony

Windows 7 (64-bit)

I recently read on another thread that TURNING OFF RULERS would help. Sounded crazy - but it worked. Too bad I like to use my rulers.

Called Adobe and they say there are no known issues. Bah.

This topic is about Photoshop CS6. Drawing rulers is an issue with Photoshop CC 2015.

Sorry that the tech support person you spoke to wasn't up to date on known issues.

We can't say when dot releases (or any releases for that matter) will be available.
