P: 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 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

    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 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

    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.

    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.

    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:

    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).
