Well, _that_ ain't right, John! (Duh! :-) )
That dreadful amount of sluggishness suggests a severe system
bottleneck somewhere, or something's just broken. I was using CS5
(circa 2010 version) prior to a recent CC upgrade to edit my 645Z .dng
files (converted to layered TIFF by Lightroom) and responsiveness was
always quite snappy. Nothing at all like what you are describing.
On paper your system sounds like it should be a speed demon. Have you
tried profiling the system with any general purpose benchmarking apps
to exercise the various pipes?
I have not run bench-marking apps. A friend who builds systems for other
photographers gave me the parts-list he used when he built his own system. His
system was fast and he does a lot of heavy Photoshop. I assembled a system
almost identical to his.
He's the go-to guy at PPNC for Photoshop and winning print competitions.
I knew the system would be fast, but I didn't think I was going to need to know
just how fast, so I never bench-marked it. It was fast when I originally built
it. It was everything I hoped for.
It was slightly faster after I installed the nVidia card.
It may have been even faster when I switched over to SSDs for the boot & scratch
disks (although I didn't run it in that configuration long enough to have a lot
of experience before attempting the Windows 10 "upgrade").
Is your SSD scratch drive large enough to not fill up when working
with the large layered files? Have you accidentally configured Ps to
put any one of its scratch files onto a slow device? Ps will use all
the file locations you mention to it, so you could remove them all and
just give it one to work with.
Photoshop is configured to use only the dedicated SSD for its scratch file, but
I'll have to look into whether that disk is large enough. I built this when the
K-3 was the top of the line Pentax. With 24GB RAM, it hardly ever used the
scratch disk working on K-3 files.
Photoshop settings says it should run best if it's allocated 16GB - 21GB of the
available RAM. I have it allocated 21GB.
Have you enabled any advanced device features for a peripheral (eg the
nVidia) which it actually cannot handle well? You might try turning
off any special features like the GPU to see what effect that has.
I don't think I have, but that's another area I will investigate. When I first
installed the nVidia card Photoshop was working properly with it. I originally
built the system with spinny drives and later switched to the SSD drives.
Photoshop ran well on the SSD drives with Windows 7 before I attempted to
install Windows 10, although I didn't notice any particular speed boost from
switching to the SSDs. But I hadn't run any benchmarks to quantify it.
The Windows 10 "upgrade" was an absolute disaster and the problems that made it
fail were similar to what I'm experiencing with Photoshop now, but hundreds of
times worse. That may have made changes to video settings that got left behind
when I reverted to Windows 7. I guess I'm going to have to dig out users manuals.
Since Windows 10 failed, the system has been a dog & almost unusable. It may
have done something to the video card settings.
It sure shouldn't be acting like you're seeing, John. My sympathies;
most frustrating, I know.
