I have a 1920x1080 screen.

Exiftool reports on my Pentax K10D raw PEF file:
[MakerNotes]    0x0002 Preview Image Size              : 640x480
[MakerNotes]    0x0039 Raw Image Size                  : 3872x2592
[Composite]          - Image Size                      : 3936x2624

When I extract the embedded JPEG image I find that it has a resolution of
3872x2592
$ exiftool -b -JpgFromRaw amsterdam.pef > jpg.jpg
$ identify jpg.jpg
jpg.jpg JPEG 3872x2592 3872x2592+0+0 8-bit DirectClass 1.417MB 0.000u 0:00.000

In digiKam 3.1.0, when "Show embedded preview loads full-sized image" is
disabled, previews load as fast as in Geeqie.

I wish that button's name was not so vague and detached from reality.
