But oh my giddy aunt it is SO SLOOOOW* :-(
Running Win7 on i3 with 8Gb RAM, 1080p LED 2ndary monitor. Not the best setup in the world, granted, but LR3 flew on it. LR4 is like going back 5 years in time.
I assumed you were working on fixing this, but when I saw your response to speed complaints for the 4.2RC that "no-one is complaining about speed" I realised I needed to make a profile, log in, and let you know. Please oh please fix the performance issues.
The weird thing is that CS6 runs way faster than CS3 did, on the same hardware. LR4, h3ll no.
LR4 is lightyears (haha) ahead of LR3 in terms of features and what the pics look like coming out of there. But. it. is. so. slow.
* Main speed issues are:
- going to and from Develop module from grid view. I get a black bar at the top of the screen, so I go make coffee and wait for it to come right.
- the preview pane top left takes so long to update when hovering over a preset that I don't bother to use it any more
- during use, everything just slows down (memory leak?) so I reset my machine every tea or coffee break to keep the performance going. Never had to do this with LR3.
