Speed still sucks big time.
that is not MP fault but Apples ( what camera are you using) and could be Nikons fault as well
In every Nikon RAW image there is a basic full size jpeg , but Apple cannot/is not allowed to use that to preview so it has to render the complete raw and built a thumbnail.
programs as Photomechanic have found a way to use the inclosed jpeg and are a lot faster in this respect...
One other oddity: the thumbnail viewer defaults to rows of 8 (24" Eizo). When I reduce the number per row, to say 4, it gives me 4 images per row but the images size remains basically the same as the 8 per row thumb. Adding more images per row obviously reduces the thumb size, while decreasing the per row number doesn't seem to increase image size. I don't understand the reasoning behind this. Guess I would need to adjust to this program's quirkiness, because it isn't going to adjust to me; or just send the program to the trash bin.
yes i also find it a quirk...also the max size could be made into 1280px
i would suggest this way of dealing with the situation:
on making a catalogue ; start with an empty one and put the thumbnails size to 640px ( max)
now throw your raws in....

The problem with this very nice program is:
It has been sold first to microsoft- they did some good things to it then they changed their view on the future and sold it to Phase one-
Phase One basically only changed the appearance and enlarged the maximum size of the catalogue.
Now Phase one seems to abandon it- or at least do not make any effort improving it.
It is also very depending on the support it gets from the OS for making the tumbnails.
on the bright side you can say it works very nice and it works since a very longtime.
If you had your catalogue in Aperture - you have a problem
If you have your catalogue in LR- you might have a problem in the future if you cannot buy it anymore, but have to pay every month to open it.
