Photoshop memory usage


Recommended Posts

My friend has an almost identical PC setup to myself, with the same memory (16GB), the same SSD discs with similar free space on all drives, the same processor, Windows 10 etc...but is having real problems with the speed of use.

I have compared all preferences in PS and these are also set the same, including the values for amount of memory to use etc.

On my setup - I select a file in LR  to edit in PS and once loaded, check in the task manager it shows that PS is using about 2.5Gb memory. When done on her PC - the system shows over 10Gb being used. 

I've checked that nothing else is running; tried multiple images, tried RAW straight from import images, previously edited .tifs etc, but always this huge discrepancy in memory usage. 

Any ideas what could be going on?

Video Cards the same? Drivers the same revision? Sometimes a person will have a computer, such as a laptop, that has two video cards installed and Photoshop is using the lower-powered one, which uses the RAM instead of dedicated Video Memory. Adobe’s products are utilizing the Video GPU more-and-more. Believe it or not, the choice of buying a better GPU is more important than the CPU. The thinking of, I have a fast CPU, lots of RAM and a big HD, so my computer is more-better-er is from 30+ years ago. This no longer applies heading into 2025.

Also, if you load images into Lightroom and then Photoshop, make sure LR is setup properly in the "External Editing" Tab. You want to make sure you are at 8 Bit.

Speaking of which, double-check ALL of your PS Settings, on both your computer and your friend's. Follow this article from top-to-bottom:
