With your use case, I would go with 64GB if it was me. If you don't need it now, you will appreciate it in a few years when your picture becomes larger in size.

There is way too many RAM Police on this forum. Not sure what is up with them.

You can check this video for a performance comparison between 32 and 64
He's talking about the graphics performance rather than memory performance.

Zooming with the trackpad is too intensive on the GPU with that many images open. The keyboard rules for this kind of navigation and frees up the GPU.

Can also disable the zooming effect in Photoshop prefs so that the keyboard command snaps directly to the right zoom level without an animation.

You can check this one than:

He plays with the picture with a 16GB vs a 32GB. More ram is better if your file a large. I think OP said everything was running smoothly with his 64GB. You will take a performance hit if the computer needs to swap stuff in and out.

Anyway, too much RAM never hurt (except the wallet).

He's not using the same kind giant file that gobbled up CPU and memory. He opened many medium res files.

I know it sounds like it would be equally intense, but it isn't. Not even close because of the way Photoshop manages the tabs.

No, it doesn't "sound like it" to me. That's why I pointed him to the video so he can see different workloads and results and judge for himself. But if I was doing any Adobe stuff myself I would still go with 64GB. Picture grow in size every year with all the new sensors. I was seeing a guy taking pictures with a 100MP camera, and that was like 2 years ago now. Worst case you can also upgrade your machine depending on how you see things.

A machine I built-in 2013 had 32GB RAM, one in 2016 had 64GB, I don't think 64GB ram in 2021 (soon to be 2022) is "crazy" in any shape or form. Personally, I know that I don't need 64GB as I can run things remotely, so I went with 32GB.

Yeah Yeah, unify and swap is quick, yeah, I know.
 
I have reinstalled all and yes I on latest m1 photoshop and not indexing now and still the same. The first 10\15 images it loads are perfect and then its all downhill from there!

Depends what images he is working with. For example in the case of web/blog/ecom photography, image resolutions have barely changed in the last 10 years. The photographers generally crop and export from Capture One at lower resolution than what the camera shoots.

that clearly shows to me that it's memory

I have in front of me 36 megapixel images that I am working on. They are 250-300MB tiffs.

I can open several dozen without any slowdown.

Each image has 3 or 4 photo layers and on top about 7-8 adjustment layers.

Other things to consider:

How many apps do you have open?
How much resources are those other apps using?
Etc etc

So its very clear that the first dozen or som images I open smoothly zoom in and out super quick with the trackpad but any more and JUST those new ones don't go smooth at all HOWEVER the first ones still do!! So they must be allocated the memory or something? Activity monitor show flat green with spare memory though! Im confused
 
The command and +\- is instant though but if I spending this kinda money I want the same results at least as my i9! and I use the trackpad a lot on this

There's nothing more I can add or say.

The pinch to zoom feature was never intended for this kind of thing. It was for casual users. Professional users use keyboard commands.
 
PLUS if I keep trying to zoom in on the later images then it gets stuck totally and will NOT zoom in or out at all using the trackpad! But the keyboard will still work and the other first images will still work smoothly with the trackpad! My OCD is kicking in!! lol
 
So do you think I have a dodgy laptop? I am sending it back

No you don't. Your expectation and use isn't optimal.

You must also know that Photoshop's gestures aren't using the same Metal graphics engine that the rest of the operating system uses. So pinch to zoom is slower in Photoshop than it is in the Preview.app.
