Anyone experiencing Intermittent high CPU usage with LRCC 2015? I've been experiencing this since upgrading to the 2015 version of LR.
I've finally gotten time to sit down and work with the new version and at time LR isn'r real responsive and when I look at CPU usage, it's running very High.
I'm on a Mac Pro with a 6 core 3.33 GHz Cpu, 32 GB of memory. I had no problems with previous versions of LR.
Try turning off the Graphic processor feature and see if it still happens.
