Photoshop CS6 is slow on my iMac

I’ve just bought and installed Photoshop CS6 (I was on CS 5.1 before). But what a pity on my Mac !! A lot of actions take between 1 and 4 sec. to be done with de multicoloured wheel : zoom, open pref pane, ⌘Z, create new doc... Unfortunately, I cannot work with this version.
Informations :
1. I don’t work on heavy documents
2. My config. : iMac 27’, 3.4 GHz i7, 16 Go RAM, AMD Radeon HD 6970M 2048 Mo, SSD, Mac OS 10.8.5
3. What I’ve tried : update CS6 (no change, except Photoshop icon that is now ugly !), GPU’s disabled in preferences (it’s worth)

Is there a solution ?

Maybe reading this provides some help in improving Photoshop’s performance.

Since Photoshop CS6 is about the same speed as CS5, and CS4 before it...

What else on your system might be causing slowdowns?
Antivirus software?
Third party plugins?
Font management software?

And the CS6 icons didn't change, so I'm not sure what you mean about an "icon that is now ugly".

Hello, and thank you.

@christoph pfaffenbichler
I’ve already read this link and try the most of the things written. I’ve just try an other thing, see below.

@Chris Cox
CS5 was fast and CS6 not. When I wrote « icon that is now ugly » it was to say that she was « broken » : she was a little bit smaller after the upgrade, with some blur and a dotted black line at the top of the icon...

This broken icon make me think that there was to be something wrong with the upgrade. So I’ve uninstall Photoshop, install again and made the upgrade again. It seem to have solve almost all the problems and the icon is good now. I haven’t use a lot Photoshop since I’ve done it and especially, I haven’t used heavy features, but it’s faster. I think it’s good, except for two thing that are a little bit frustrating : the zoom tool and the hand tool :
1. I use a lot the magnifying glass tool with the shortcut ⌘space to draw a rectangle on the area I want to zoom (I don’t use the 3d option « zoom défilant » in french). In Photoshop CS6 it take between 1 and 2 sec. after having release the mousse button ! It is not blocking, but it is awkward !
2. after having release the mousse button I’ve the hand tool on the screen (and it’s really the tool that is acting), not the previous tool (before zooming), even if it’s the previous tool that is selected in the tool window. The only way to get my previous tool back is by using the space bar.

As I wrote before, these 2 problems are frustrating. Is there a way to solve them ?

The upgrades haven't changed the icon. And there shouldn't be any blur or a dotted line.

1. Sounds like a video driver problem, but we haven't seen too much of that on MacOS (but 10.9 does have problems on certain machines). But we haven't had other users reporting such a slowdown. You could try setting the GPU mode to "Basic" in Photoshop's performance preferences, then relaunch Photoshop and see if that helps. The next diagnostic step would be to turn off GPU acceleration in preferences and relaunch Photoshop.

2. That could be related to a MacOS bug we've been working with Apple on -- the WhiteWindowWorkaround plugin might help with that.

1. I’ve tried the GPU options and turn off the GPU : it is worse... Since today I’ve only seen this problem on the zoom with the rectangle for selecting an area. Other methods of zoom aren’t impacted.
2. Thank you, but this plugin hasn’t solve the problem. it is not too awkward since which I can change tool with the spacebar...

Alright, something is very weird on your system. Other Photoshop users haven't reported issues like that. My guess would be some sort of utility software, or a problem with the OS install (like if you ran any sort of "cleaner" software that damaged the OS).
