Hello. I have a weird problem with LR 4.3 when using the development module. When a RAW file loads, it would take a second to load (and says "loading"), after which the photo would be sharp, but then the photo would turns soft again, and after about 5 seconds it would become sharp again. The problem persist for both standard and 1:1 previews. Standard preview is set for 2048 pixel, and the display is set to "fit" screen.
My hardware:
Monitor: 2560x1600.
CPU: i7 950
RAM: 12 GB
Video card: ATI Radeon HD4600 series
OS: win7 Pro SP1.
LR 4.3 is installed on a didicated SSD. The catelogs are also installed on the same dedicated SSD.
I would appreciate some suggestions. I have to edit 500+ photos day. Waiting 5 seconds for each photo to become sharp adds 40+ minutes of wasted time. Please help, thanks.
