I just built a 4790k desktop with Samsung 850 Pro and using built-in GPU on processor. I was hoping after upgrading from 6-year-old computer that there would be no delay when flipping through photos in develop module after importing the photos for the first time. The delay isn't terrible (probably a second or two while it loads into full resolution), but I thought utilizing one of the fastest processors and a very fast SSD would make everything instantaneous. I read that a dedicated GPU will not make a difference in Lightroom's develop module. My photos are 16MP Olympus RAW files from an E-P5. This is Lightroom 5.7.1. Any idea what component is holding me back? Thank you.
