Question

Photoshop uses an extreme amount of RAM on M1 Pro

Hi! 

I am using Photoshop on a M1 Pro 16" Macbook Pro and its eating up all of my ram. I currently have one project open with 13 layers, the whole file is about 700 mb but photoshop uses 28,58 GB of memory slowing down the entire system (I have 32 gigs). It is the apple silicon optimiesd version of photoshop (I have reinstalled to make sure and it says "Apple" under process type) and the Photoshop version is 23.2.0 but this has been going on for the past few months since I got the computer. In Photoshop settings I have a cap of 20gb. 

What might be wrong here? I guess it's some bug in photoshop?

Hmmmm....how much % of the RAM do you have alloted to Photoshop?  To check, click on Photoshop then click on Preferences, then click on Performance, There, you can allot how much of your Computer's RAM to allocate to Photoshop.  If it's 80% or more, its going to use that much RAM of your device

It's 19456 MB (70%), so thought the usage shouldn't exceed that?

That's odd. Photoshop should never exceed the limit set in Preferences. That's the whole point of having that setting, and normally this is a brick wall.

 

Monitor memory usage over time (10 minutes or so should do). Does it hold steady, as it should, or is it steadily increasing without you doing anything? If the latter, it sounds like a memory leak, which is a very rare occurrence nowadays, but can happen with badly written plugins etc (and probably also drivers).

 

But note that plugins (including Camera Raw) run outside Photoshop's address space and use their own memory.
