Shot a 5 shot series, plus or minus 2, plus or minus 1 and normal with Olympus OM-D E-M1, off a tripod. The RAWs are "ORF" format.
With Auto Align, Auto Contrast and deghosting turned off, it took about 90 seconds to get the preview up to merge. Merging in LR took another 45-60 seconds with virtually no "HDR" effect per se.
Range of develop sliders is the same as if I had used Photoshop Merge to HDR Pro of left it in 32 bit TIFF so this DNG is probably a 32 bit image wrapped in a DNG format.
I like LR very much but this implementation of supposed HDR seems to miss the mark badly.
totally agree, why add a feature thats basically useless? i feel like im back in 1999

To Preview Merge Total Time
LR CC 2015 Merge to HDR: 62 sec. 20 sec. 82 sec.
PS CC 2014 HDR Pro: 70 sec. 14 sec. 84 sec.
(Using LR Edit In & 32 bit Mode)
The two images as processed in LR Develop module look nearly identical. You need to crank up the -Highlights and +Shadows to achieve HDR recovery.
