Photoshop: CS6 very slow and unresponsive on my system

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That sounds like it could be just an out of date video card driver (bugs in the driver cause slowdowns in drawing).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.

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 .

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...

Here it starts to lag alot whenever a document is open, even a small new document with no layers, here is a video :

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

Update : i solved it by enabling a windows 7 Aero theme !

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.

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.

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

Disabling "Use GPU" in Edit > Preferences > Performance worked for my issue.

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.
