    Lightrooom CC slow performance in Develop Module on iMac 27-inch 5K Display Late 2015


      I am using Lightroom CC on 27-inch iMac with Retina 5K display,

      (4.0 GHz QC i7, TB upto 4.2 GHz),

      16GB RAM, 3 TB Fusion Drive,

      AMD Radeon R9 M395 w/2GB.


      Lightroom CC works quite slow in develop module. E.g. applying brush stroke takes a while and I have to wait as it slowly renders applied brush. I did not had similar issues with previous version of Lightroom on Windows computer. I checked that GPU acceleration is turned on. Internet search shows that this issue exists for few people, but I could not find any solution. Is there anybody in the same boat? Is there anyone who has found any fix for this?


      Please.. Need your help desperately..


      Thanks & Regards,
