Photoshop is extremely slow with large files. I've tried everything I could think of, need help.

Hi,

one of the computers at our office is having a variety of issues with Photoshop, the combination of which are making it basically unusable at this point.

First, let me list the specs of the hardware, then I'll go through the list of problems and list all the ways I've attempted to fix it:

Hardware:

i7 5820k

32GB DDR4

GTX 980

250GB Samsung 840 Evo (+ storage drives, which aren't used for Photoshop though)

Windows 10

The PC started becoming unusably slow with complex .PSD and especially large .PSB files, to the point where toggling the visibility on a single layer takes 5-10 seconds to respond at all. Zooming in and out will result in Photoshop freezing for several seconds with every step.

Worst of all, saving a large .PSB takes more than an hour. It will just stay stuck at 0% for an hour and then save the file within another 10 minutes or so. This is saving locally to an SSD, although saving to the NAS doesn't seem to be much slower. The file in question is 6GB in size, large, but nothing we haven't seen and worked with before. Photoshop is fairly slow on this PC in general, but this specific file is where it really just gives up.

Here's a list of things I already tried:

-allocated more RAM to photoshop, currently allowing it 26 of 32GB.

-clean install of photoshop

-updated graphics drivers

-clean install of windows 10

-tried photoshop CC 2014, all versions of CC 2015 and CC 2017, all had the same exact problems

-swapped out the GTX 980 for an older GTX 760, reinstalled drivers accordingly

-deactivated GPU acceleration

The only thing that made a difference was deactivating GPU acceleration. Even though the performance is obviously not good without the GPU, it responds within less than a second and is somewhat usable compared to having GPU acceleration enabled.

Obviosuly though, this was not the solution I was hoping for. Since I have gone through several versions of Photoshop and even a complete fresh install of windows, the most logical next step (AFAIK, at least) would be to suspect the GPU. But even after swapping it out for an entirely different one, the problem persists.

So now I'm out of ideas and need help figuring out what could be causing this.

If anyone has any ideas, please let me know. At this point I'm fairly certain I have a hardware issue, I just can't figure out what component could be causing the problem.

I also have pretty much the same setup . Did you run samsungs magician and set it for performance If so, go into windows services and enable superfetch. On my 6 core I7 it helps. Other than that it is a glitch in PS.

I'll give that a try as soon as I get the chance (the PC in question is currently in use). But since photoshop seems to be performing normally with GPU acceleration turned off, I suspect that the problem isn't CPU- or SSD-related. I've tried saving to all kinds of drives, including network drives, and the speeds at which it saves don't change until I turn off GPU acceleration. Same for the overall performance.
