D800e files in ViewNX 2.51

Well I don't know what is going on with your computer, but I just tried converting 8 D800e raw files to jpeg using ViewNX 2.50 and it took 55 seconds to convert all 8 files, or 6.875 sec per file.  I have essentially the same computer as you HP desktop,  i7 Quad, 8GB memory, 3.4 GHZ intel processor.  I am using a SSD, but I don't think that is making that much of a difference in speed.  Editing seems to also take only a few seconds to update.

I used to use Capture NX2, but recently bought Lightroom 4, and am loving it.

Sorry I can't be more specific -- Fred
