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.

    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 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.

    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.

    No updates that we can share. Any updates are going to come in Apple OS updates to the current MacOS version.

    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.

    Apple does not pre-announce the dates of their OS updates.

    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...
