Windows 10 Pro, 64 bit. 5820 running at 4.5 GHz, 32GB of fast memory, nVidia 970 GTX, O/S, scratch, temps and all that on a 1TB SSD. Images on a 4TB Raid 0 with 7200 rpm drives.
There's been NO new hardware. No REMOVED hardware. No reconfigured hardware. No KNOWN major O/S updates since prior to the Photoshop upgrade.
Nothing has changed in the workflow... Using PS on exactly the same type of images I was previously - Nikon D500, D810, and now also D850. The ONLY things running when I'm editing are Outlook, Lightroom (NOT upgraded yet because of some of the horror stories) and Photoshop.
Let Adobe CC do the upgrade to Adobe Raw, Bridge and Photoshop to the current version from the previous version. In previous version Photoshop ran adequately. Not blinding fast (sub-second) doing anything significant, but reasonably well. Using a simple tool like the crop tool, movements were smooth and quick, with no perceptible lag time. Same for the Free Transform tool. Even rolling the mouse wheel to resize was pretty good.
NOW, (without going into the other things that no longer work well, the crop tool has a significant lag between moving the cursor and having the crop change, and the movement, when it DOES occur, is choppy. Exactly the same thing with the Free Transform. And, of course for the mouse wheel resizing. And I suspect for a lot of other things I haven't hit yet, having just upgraded.
I've SEEN the "Optimize Performance Photoshop CC" stuff, and DID THAT in the past. It ran FINE....... Went through it AGAIN today to see if there was anything I'd missed. I don't see anything to REASONABLY change:
General, Interface: I don't see anything to change there
Workspace: Auto-show hidden panels, Open as tabs, Enable docking, nothing new there
Tools: Nothing I can see that should cause a problem - Enable flick panning, zoom with scroll wheel, animated zoom, zoom resizes windows
History Log, File Handling, Export - all nothing
Performance: Of the 32GB of ram, of which it SAYS there's about 24 GB available I'm giving it 18. It recommended 15.7, so I started there, but nothing between there and 18 has made any difference.
Optimize cache and tile size is set for "huge pixel dimensions" since I'm shooting D810 and D850. 100 history states (this is DOWN from the normal 150 'cause I sometimes need to go back A LONG WAY in history. Making it smaller did NOTHING.), 6 cache levels, 1024 tile size
In the Graphics Processor it recognizes the Nvidia GeForce GTX 970/SSE2, has it turned on, and it WAS set to Advanced, "Use Graphics Process to Accelerate" and "Anti-alias Guides and Paths". Since the optimization document recommended that if performance sucked in Advanced, turn it down to "Normal". I DID. NO CHANGE. Again, this has been working PERFECTLY in Advanced for umpteen versions......
I don't see ANYTHING in performance that should be a problem... Is there SOMETHING I'm not seeing?
Scratch Disks: It's got 2. 1 is the internal SSD where there's about 100GB available for scratch. 2 is an internal hard drive that IS NOT USED DURING ANY OF THE PHOTO EDITING where there is approximately 400GB of free space. The SSD has the O/S and other software on it, but I've ALSO TRIED a USB3 SSD with 125GB available, and NONE of the above have made any difference.
Cursors, Transparency, Units, Guides - I don't see anything there that should be having this effect
Plug-Ins: Enable Generator OFF. Enable remote connections OFF, Allow extension to connect OFF, Load extension panels OFF. Don't see anything there.
Type: nothing I can see...
3D: I'm not doing 3D so I'm not sure how this would affect anything but if there's something bizarre that needs to be set in there, let me know.
Technology Previews: Everything is turned off....
I don't recall EVER seeing the Efficiency indicator go below 100%, but I'm guessing MUST have at times 'cause prior to the update it wasn't unusual to have a half dozen D810 images open depending on what I was doing. But, in any case, IT WORKED, now IT DOESN'T. Only known change IS THE UPDATE.
What do now? I can go back, but does PS need to know anything to work with D850 images? As long as Bridge and ACR are current will it work? Is there something I can reconfigure? Or is this version of PS just a pig and we're back to the kind of slow, choppy, laggy performance we sometimes got with new versions back in the CS? days? I can't imagine that or there'd be a HUGE outcry, complete with tar and pitchforks, and I'm not seeing that. SO, what do now?
