Dear All,

I downloaded and am using the most recent Photoshop Beta Version and I must say that I am noticing a noticeable improvement - it is somehow smoother, and responds faster in most of the commands.

I look forward to having the full version.  Congrats to the team!

I would like to ask a question I have been having on my imac whilst post processing on any version of Photoshop - maybe someone can assist me improve this problem of mine:

I use an imac 3.6 GHz 8-Core Intel Core i9 with a Radeon Pro 575X 4 GB graphic card + 64 GB 2667 MHz DDR4 Ram.

I am a photographer by profession and when I load more than 20 or so images for post processing and resizing everything slows down re:  resizing tool, etc.  I know I am loading it quite a lot and I do think it has to do with the graphic card.

Can I have adjust some settings which maybe can help?

Cheers and thanks

DA

Hi Dominica.  I don't think the GPU would have much impact in what you are describing.  It will be more to do with how much RAM you have, and your Scratch Disk arrangement.  

 

Does your imac only have the one drive?  Next time things have slowed down, check out the root directly of your Scratch drive, and note the total size of the Photoshop Temp files.  If you have a number of full res files open at the same time, then I suspect those temp files are going to be tens of gigabytes, and photoshop will have to read and write to the drive as you move from file to file.  As you can imagine, the performance of that drive is going to make a lot of difference.  Especially if the same drive holds your OS and program files.

 

You do have some control of how Photoshop handles your files in Preferences > Performance >Cache

Scroll down this page to Adjust Cashe Levels.

@Trevor.Dennis - Thanks for your kind response.  Much appreciated and so kind of you Trevor.

Yes my main scratch disk is the mother mac drive which incorporates my OS and program files.  I wonder if changing to an SSD drive would be more convenient or possibly another drive.

Re:  Photoshop Temp files, I never did have a look at my root directory of my mac mother scratch disk - if so do I delete these Temp files?

Attached find a screenshot of my preferences settings.

Would appreciate any kind of assistance.

Thanks

Unfortunately, I am not a Mac user and unfamiliar with your iMac's performance, but the specs you've included look capable enough.  If you only have the one drive, then that is going to impact performance when working on large documents.  You can gauge this by the size of the Photoshop Temp file(s).  I just checked, and having lots of image files open at once had less impact on the temp size than I expected.  I opened a dozen Canon R7 RAW files on top of the half dozen low(ish) resolution, but multi-layered files I already had open, and it only increased the temp file size from 8Gb to 15Gb.  It didn't eat up much RAM either, and we have a similar amount of RAM.

Photoshop Temp files should all be deleted when you close Photoshop, but if Photoshop ever closes through a crash or freeze, then the temp files can be orphaned behind clogging up your drive, so if you see any when Photoshop is closed, or if they have other than today's date, you can safely delete them.

 

I'm going to change your subject line to show you are using an iMac and that this thread is unsolved.  That should attract people with more expertise on your specific situation.  I have not worked as a photographer for several years now and am a bit out of touch with processing a couple of thousand images at once, but I think I could easily do so without any noticeable loss of performance with my Windows system.  So lets see if we can scare up a Mac user for an opinion.

 

We need to know what OS version you are using?  Venturer, Senoma?

@Trevor.Dennis again so very kind of you!

I have taken note of all your notifications so thanks again.

Yes that would be nice to change my subject line showing I am a Mac user using Senoma 14.4.1 version.

Cheers and thanks again!
