I never use the Finder so I never knew the speed of rendering DNG previews there.
I just went to the Finder and I was surprised to find the rendering was the same speed there as in PF8.
What really confuses me is in PF7 the rendering is almost instantaneous. Which is what I’m very used to and gave me the idea to comment.
So what did PF7 have undertake hood that would allow this that PF8 does not?
If it matters I’m using El Capitan but the rendering was fast in all the other OS versions before that as well.
I hope you can figure out how to make PF8 the same speed as PF7 since I use DNG files all the time.
