Lightroom 6-CC notes
 

I watched some tutorials, and I like the new Lightroom enough that
I'll probably go back to using it. There are enough new features over
LR 4 that it can replace the software I've been using.

Back to the tutorials, there is one page that Savageduck recommended:

http://www.jkost.com/lightroom.html

That page alone had enough tutorials to cover just about everything I
normally do. But then this issue comes up: If you are using LR 6, go
to the dust and spot removal video on that page. You will probably
learn something about improved features, but you will also see the
screen update instantly when dragging the source spots for cloning or
healing. When I do that, there is a lot of latency, and sometimes it
barely reacts at all. I Googled this issue, and I'm not the only one.
In fact, I was heading out the door to buy a new mobo to start the
upgrade of my computer to an I7, with 16 GB of memory, but then ran
across a poster with the exact setup I was looking to change to, and
he has the exact same issue.

Anyway, one of the first things that everyone hears about LR6 is to go
into the performance tab of preferences, and check the "use GPU" box.
But while looking at the threads on this issue, it comes out that
doing that might actually hurt your performance in most of the tasks,
and help with almost nothing. So if you have the same problem as me,
try unchecking that box. It made no difference on my computer, but it
does help on some. And everyone seemed to mention that with that
checked, photos seem to render twice, which slows things down, too.
That does happen on mine.

This problem isn't a deal killer, and I like PS CC too, and I expect
updates to fix this issue at some point.

Does anyone have any tweaks to improve graphics performance? I have a
quad core processor at 2.5 GH, 8 GB memory, an SSD with AHCI
activated, and Win 8.1. It's getting a bit old, but I would still
expect it to perform better than it does in LR. And I did update to
the newest video card drivers. And I torture this computer with audio
production and editing software, running multiple effects and
plug-ins, and it never chokes.
