I’ve tried checking and unchecking GPU, but it’s had no effect on the grid scrolling. I just don’t know if adding RAM will help that specific thing, or if grid scrolling is a video memory issue. I hate to spend $140 on memory and have it not help the scrolling issue.
I have a new Mac Pro with 32MB ram and an internal SSD. The application is on the drive, pictures on a LaCie 4 TB external drive attached with thunderbolt. Even so, I have the same problem as rbanks88. It's counterintuitive that such a machine can not make scrolling smooth. Is this a software problem?
Grid view scrolling generally is not dependent on memory, but faster disk speed (disk where the catalog is stored) may help. Is the catalog stored on an SSD? How large is your monitor in pixels (not inches)?
