What are your Scratch Disk (Preferences > Performance) and the rest of the Performance settings?
Please read these:
Oh, I did step the ram usage to 100% again.
Are you using your start up disk as primary and only Scratch Disk?
If so you should amend that.
It was checked on both and I have tried the different combinations of options with no difference. (So, I left it at that. It is the same ssd that has been split in 2, so didn't think it made a diff.)
I have also noticed that the more layers I have, the more frequent the program freezes and the duration has also increased a bit. Not sure if that helps.
You should use an actual dedicated, separate Scratch Disk.
Have you perused the "optimise performance …" page for general Photoshop performance related advice?
OK, so I uninstalled photoshop and re installed it and saved it to my D drive. Now only adobe programs and files are on there and selected only the D drive for my scratch disk. (I hope that is what you meant.)
Yes, I have looked at the page and changed some settings (well the ones that I could understand and a few others).
But it made no difference.
(I hope that is what you meant.)
No, because if I understand correctly you are now still using the start-up disk as scratch disk.
The scratch disk should ideally be a physical disk and be used for nothing else.
Ok, so I finally got a 500gb external. And used that for my scratch disk. There is still no difference. It still takes double the time to load my drawings (16 bit).
Thanks for your help. The 8 bit designs are working fine now, will just use that. Don't really need the 16 bit.
I also loaded everything back to my D drive and made that my scratch disk again and now that seems to have refreshed something as it fixed something for the 8 bit.
Thanks once again.
Is your SSD partitioned (as both C and D drives)? Seems odd unless you plan on dual-booting or something.
Ideally, your scratch disk should be a physically separate, dedicated HD with NOTHING ELSE on it. (See next post)
Additionally, Adobe applications really, REALLY want to reside on your C: drive, together with your OS.
The rule of thumb I follow to figure out scratch space says to figure on 50 to 100 times the size of your largest file ever multiplied by the number of files you have open. I have seen the scratch file exceed 800 GB once, an admittedly rare occurrence, but it often exceeds 200 GB when stitching large panoramas and the like.
As an example—and stressing that I'm aware that others have even more scratch space than I do—I keep two dedicated, physically separate hard drives as my primary and secondary Photoshop scratch disks and a lot of GB free on my boot drive for the OS. I also have 16 GB of RAM installed.
Additionally, if you only have a single HD, i.e. your boot drive, you'd need it to be large enough to accommodate both the swap files of the OS as well as Photoshop's scratch.
