Question

Mac Studio M1 Max Slow on Photoshop

I have just switched to Mac Studio (m1 Max 64GB Ram).

 

Performances on graphics are super! comparing to a MBP i9 6-cores 2019 with 32Gb Ram, the Studio is around 5 times faster on GPU based tasks, like some filters such as iris blur, path blur etc...

 

The disappointment comes to me when on CPU based tasks, such as Median Blur for example the two machines have the exact same perfomrances. Also, when using the option "select subject" the Mac Studio can;t really cope with it, sometimes it selects random things in the corner of the images, but no the subject at all! If you then manage to get the subject selected and you go in "refine edge mode" or "selection mode" (whatever it's called) it's very laggy and not precise on the edges. When you then have refined the edges and press "enter" to obtain the selection, the colourd (apple) wheel shows up for a 2-3 second before bringin you back to the main photoshop workspace.

 

Is this something i'm just experiencing myelf or are you guys noticing the same weird behaviours in some tasks?

 

please let me know.

 

Tahnks,

    Both Select & Mask and Blur Gallery use the GPU, so it's not as simple as GPU vs. CPU.

     

    However, according to the documentation, both run under OpenCL, which may not be very well supported in MacOS these days. They will probably be rewritten for Metal, if they haven't already.

    Hi,

    Thank you very much for your reply, that's helpful to know!

    However, how do we explain that those functions run very smooth on previous Mac OS machines? (Intel based ones).

     

    Thanks

    Hi there,

     

    This is what i posted on another post and it seemed to work for some.

     

    "

    Did you migrate from your old mac to the new one with migration assistant? as if this is the case you must have imported the intel version of PS. 

    I realised this was causing me the issue, so i have unistalled PS and re-installed the latest version (also, make sure when you do cmd+i on the PS icon it says "universal" and not "intel")

    Since i have done so the select subject starts to run very smooth, quickly and precisely.

    Hope this helps!"

    Hi Damien, thank you for your answer. I did a complete clean install, and I tried different versions of Photoshop. It is so unresponsive no matter which version. Working with a file larger than 2 GB is impossible. M
