Photoshop CC 2014: Performance problems iMac Retina 5k

I've been using the new imac retina, and i have enormous problems with the performance of Photoshop. If i for example use the selective color correction, this does not run smoothly. Other functions also work delayed. I noticed if i do not use Photoshop in full screen mode, everything goes back to normal. A friend used the predecessor model imac without 5k resolution, but has no problems. I suspect Photoshop has problems with the resolution of 5k. I hope Adobe fix this problems because Photoshop works slow and delayed, the performance is terrible. I bought the retina iMac 5k, since my previous mac is getting old and slow. But now is it so, that my new retina iMac, run equal slowly as my old iMac. Adobe please fix this problems, so i cannot work.

Hi Manuel,

Let's start with a simple question:  what version of Photoshop are you using?

Have you tried changing the display preferences in Performance preferences to try Basic or Normal instead of Advanced?  I'll try to reproduce this myself first thing tomorrow morning when I have access to the 5K iMac again.  With any luck we can figure out a way to get performance back to what you'd expect asap.

Thanks,
Adam

Hi Adam, Thanks for the quick reply.
I'm using the latest version of Photoshop CC 2014 2.2.
This solution which you describe here, has been already said to me the Adobe Support. I already tried it with multiple options and settings. Unfortunately, this solution did not yield any improvement. The main problem is that the changes (for example the selective color correction) didn't work 1 to 1 as usually, but with delay.

I've noticed that these delays will occur only if the images or graphics have a size about 3.700 * 5.000px. If the resolution is smaller (for example 1.500*2.500px), the delay is not so strong.
Also when i'm zoomed in the picture, works delayed. If i zoom out far, then works normal.

I think that the problem is the resolution of 5k. I have read in forums, that other iMac Retina 5k users, report about similar problems with Photoshop and Lightroom.

Thanks,
Manuel (sorry for my bad english ;-)

Hi Manuel,

Can you tell me more about the types of images you are using? Do they have many layers, or layer comps? What's the bit depth (8, 16, or 32bit)? Do you happen to have any other applications running at the same time as PS? I ask because I've created big files on my 5K iMac and am not seeing the performance issues you describe. I'm still convinced we can find you a solution to mitigate the performance issues you're experiencing.

Thanks,
Adam

Hi Adam,

when I open an image in PS i do this via lightroom. Right-click ----> edit in ----> edit with Adobe Photoshop CC or open in Photoshop as a Smartobject.
The settings for external processing in Lightroom are: PSD, 16-bit, Profoto RGB, 240 DPI. I made a quick screen shot to show you the problem better. How do you see, delayed in zoomed mode. When i zoomed out it works 1 to 1.

Dropbox Link: https://www.dropbox.com/s/yopkyukag1m...

I hope it helps you.

Thanks
Manuel

Here is a screen capture with a photo when i use Lightroom: https://www.dropbox.com/s/6r79r2wmzx4...

I'm setting up my system to try to use your exact steps, in the meantime, can you tell me if turning off Rulers (cmd-R) speeds up performance on your system?

Also, I would suggest upgrading to 10.10.2 (which was recently released) to see if that helps as well.

I've noticed something else. When i change in my display setups on my Mac the resolution from "Default for display (looks like 2.560*1.440)" to 2.048*1.152, everything runs normal.

I have the same setup as Manuel, just Radeon 295 4GB

Maybe after upgrading to 10.10.2 is a bit better. I say, a bit. or I am getting used to it. But it is far from acceptable on such a powerful machine, though.

Strongly hope Adobe will update soon...

We're now able to reproduce the slowdown you're seeing. Now investigating what it would take to get it working better on those devices. Stay tuned for an update soon.

Thanks,

hi Adam,
Do you have any updates for us regarding the issue? I believe that 4 months is long enough to find the solution and/or develop some kind of a patch for Photoshop etc...

Thanx

There have been updates to OS X 10 since that time frame and there has been no impact on the problem for me. Can you say more? This is getting very frustrating

No, we can't say more. We are still waiting for Apple to fix the list of bugs we have documented in MacOS 10.10.

I'm having this same problem. I was expecting a major improvement after upgrading to the imac 5k and lightroom is running way slower than on my old machine. Looking forward to that update!

Oh yes, Lightroom is running so slow. With such a powerful mac computer, Lightroom should actually run faster, but unfortunately is not so. I hope it comes a update (or Lightroom 6) that we can exploit the full performance from this powerful iMac.

I think Adobe will find this problem and provide an update as soon as possible. Many users have purchased a 5k imac, and there are always more. Therefore, Adobe will soon bring an update.

Hi Adam,

have you first information about a solution of the problem with the 5k iMac 's? Does the Adobe department works already on a solution?

Thanks

I even face stuttering and a slowdown when working on JPG files with 2000x1400px at sRGB 8bit when ps fills the whole screen set to standard retina setting.

No, you launched Photoshop CC in the video, not CC 2014 (they have different splash screens).

Yes, CC is version 14, CC 2014 is version 15.

I'm really trying to make sense of what you're telling me. I reinstalled via creative cloud, my plan is active, photoshop says it's up to date, adobe says CC 2014 2.2 is the most up-to-date version ( http://blogs.adobe.com/crawlspace/201... ) which is exactly what I'm running.

You may have CC and CC 2014 installed. Make sure you're launching the 2014 version. You can confirm you've launched the correct version by selecting Help>System Info...

Any Update on this??? I just bought a 5k imac, photshop CC is unusable. Had to revert to CS6 which is a little buggy but at least usable.

The main problem is delays with the stamp tool and with the hand tool.

I've tried different combinations of graphics processor setting in CC to no avail.

Adobe and Apple know this error with the 5k iMac, and work for a solution or update? Any informations about that?

If your activate in the information of the program (Photoshop or Lightroom), the button "OPEN IN LOW RESOLUTION" the programs run much faster and without delays, or bugs. Everything works now perfectly but the resolution is now very bad and so is it only a temporary solution.

I tried the "open in low resolution" thing. Still having the exact same problems with panning with the Hand tool and a delay with the Stamp tool.

Yesterday I tried CC a brand new Mac Pro, and experienced the same issues with CC. So it's not just the 5k imacs, maybe a Yosemite issue?

I also called Adobe and they said "they've been aware of the problem for 3-4 months" and couldn't give me an estimated time that it would be resolved.

Yes, most of the video driver problems were introduced in Yosemite, and are just worse on the 5K iMac (more pixels, more time taken). Yes, we've been documenting the problems for Apple since Yosemite was introduced. Apple is aware of the problems and is working on solutions.

I've been using CS6, and it's defnitely better but I still had some issues with shortcut keys getting stuck, stamp tool getting stuck etc.

BUT

I just installed the "White Window" plugin and it seems to have solved these issues!!

Here's the link for anyone who doesn't already know about it:

That does work around some of the known MacOS issues (and the changes are already in CC 2014). But some users are seeing problems with MacOS 10.10 which that plugin cannot solve. We have documented the issues for Apple, and Apple is working on solutions.

The problem is not confined to LR and CC. I have PSE 13 on a 5K iMac (OS X 10.2.2) and the editor slows to a crawl after only a few operations (though not immediately). This happens when the PSE organizer is open, and the editor becomes unusable. (Yes, I've tried smaller window sizes, etc., with no improvement) However, if I close the organizer then the editor running by itself is fine. That doesn't sound like solely an Apple issue.

I appreciated finding some response here from Adobe. It is impossible (literally, not possible) to get any support or response from Adobe regarding PSE. I do hope that any fix they implement will be carried through to PSE 13 (not PSE 14 in six months).

Having the same issues on my 5k iMac. Pretty silly when you think about how powerful that machine is. Will be carefully watching this topic.

I bought my imac retina because I heard it works so much better to paint in Photoshop, but so far I've only been disappointed. I lowered the resolution, I run all Adobe apps in low resolution mode but I still get lag when using hand tool, eyedropper, brush or anything else. I'm extremely disappointed but don't know if the problem is my computer or the applications.

Oh, and I have 32gb RAM, i7 processor, 2gb graphics card

The lag we have seen so far on the Retina iMac 5K is due to issues in MacOS 10.10. We have documented this issues for Apple, and Apple is working on solutions. You can avoid some of the known issues by hiding rulers and the histogram palette.

I am assuming there is still no answer to this? I upgraded pretty much specifically to get better response in Photoshop and it's way worse.

Really?
Is it really Apple issue? It's easy to say like that. I run a lot of Apple apps including pro apps and no performance issues at all. (iMac 5K, 4GHz i7 8GB Ram, 256SSD, Radeon 295X 4GB)

No, it takes a lot of time to debug and test the OS issues in order to say that. Oh, and we actually did spend that time to track down Apple's OS bugs.
