Just stumbled across this. I have a Nikon D800 and have found, until now, that Lightroom on my 6-core MacPro was really slow and laggy. 4.3 seems to have significantly boosted performance for processing the huge RAW files coming from this camera. I'm not sure if it's because simply the act of upgrading cleared something out, or if 4.3 is that much better, but that's the end result!
