In Bridge the photos show up right away but it's waiting for the "thumbnail extractions" to complete that takes so long for me and the files are slow to view till that's done. I thought that was normal for Bridge but maybe I do have some issues ?
Are you sure you aren't referring to "Preview extractions"?
In other words, thumbnails show up quite quickly, but then "behind the scenes" larger previews are being rendered for all the files in the folder, sure, it takes a bit of time but I've never seen it as interrupting my workflow. The "thumbnails" are there at a glance, and if I open a Raw file in Camera Raw it does so fairly quickly even while the previews are in the process of being rendered...
All that being said I don't have one of the newer super-megapixel cameras, I'm sure things do slow down a bit with the huge files!
At any rate, even if Bridge takes a "bit" to render and use the larger previews, I don't see it worth the time and effort to open/use another app then switch over (except I use Lightroom, not Bridge)!
