    LR 6 Performance issue

    MarkRomine Level 1

      I now have a 5K iMac 4Ghz i7 that will Turbo Boost up to 4.2 Ghz, 32GB Ram and I'm so disappointed with LR 6 performance even with Smart Previews @ 1:1 running under OS 10.5.5 Yosemite. I have the 'Use Graphics Processor' checked and I have the ADM Radeon R9 M295x card installed. I have Standard Preview size set to 1024 px and Preview Quality set to 1:1. This thing is barely running faster than my 5 year hexcore MacPro with 24GB of Ram. I'm constantly getting spinning beach balls on the new machine while working in the Develop window.
