Photoshop Becomming slow with large document format.

Hello!

Im working on a large file at the moment in Photoshop and im having a bit of lag and slowdown.

The document that im working on now is 7000x7000 pixels 300dpi and around 70 layers so it might not be a surprise that im having issues but at the same time I have a pretty powerful computer ( 32 gig ram and i7-9700K CPU @ 3.60GHz processor and Ge-Force GTX 2060 Graphics Card).

So I dont know if my document is simply to big/taxing or if i have a a setting wrong on my computer/photoshop or if I might be in need of a reformat on my computer..

Iv'e tried variuos settings on the performance tab in photoshop to some sucess, Iv'e heard that Photoshop has actually become worse in handling large formats compared to the 2015 version? I also had one problem where Photoshop simply would not save, it was stuck at 0 Percent.

Any way, any feedback would be most helpful!

The one single overriding consideration when working with large files is the scratch disk. It's more important than anything else. There is no such thing as "enough RAM", no matter how much you have. So Photoshop needs to write temporary working data to disk. That's the scratch disk.

Scratch files can easily grow to 100s of gigabytes, and anything less than 500 GB free disk space is a potential problem. In some cases you may even need up to a terabyte.

If the scratch disk is on a spinning HD, it will be slow. For best Photoshop performance, you should use an NVMe drive (aka PCIe M.2).

I have posted in bugs, but found an issue comparable. So just put my thread also in this topic.

When saving files from adobe photoshop cc 21, cc22, cc23, it will last 90 seconds. File size is about 1,5 Gb. This issue is there since two weeks. It appears when there is more then 1 layer. Also with psb files. When saving same file as tiff, it is normal (about 2 seconds). Also adobe raw is very slow. I have had chat with adobe for more then 3 hours, but no solutio till now. case number ADB-26706242-D1H5

workaround: Mac studio m1-ultra, 128gb int. mem., 2Tb int. pcie-ssd (nvme-apple silicon), Macos monterey 12.6. Upgrade to Ventura at the moment not possible, because of use softraid, incompatible at the moment.

75% of memory allocated to Photoshop, benchmark of drive is 6500 gb/s writing and reading speed. 300gb free space, scratch disk is other partition, 400gb free space

Are there more people having this issue? Solution?

Thanks in forward, with kind greetings, Ferdinand Bennink, Compleetinbeeld

If you have compression on with PSD/PSB, and compression off with TIFF, that could account for the difference. Compression is a massive slowdown especially with large files, and particularly if you have layers. Going from 10 seconds uncompressed to 90 seconds compressed is not uncommon.

Many of us turn PSD/PSB compression off in preferences, for this reason.

Please post only once, you won't get any more answers with duplicate threads, it just adds confusion.

Hi!

How much of your RAM have you allocated to Photoshop? And, do you have any external Scratch Disks hooked up to allieveate some of the processing power if it's using your CPU? Also, have you tried resetting your preferences? Here is a document to help: Preferences

I apologize that I don't have a fix for the slowness issue, but I have a possible suggestion as a work around. Is your document built in such a way that you can split it up into objects that can be worked on separately in a new document and then integrated into the whole file? You could use a flattened background to be able to refer to your original file, but not have all the weight of the large file to deal with.

Let us know if that helps,

Michelle
