Machine is an iMac (Big Sur) w/40gb RAM. PS set to 60% RAM Usage.
I have a 500gb SSD Hard Drive with 300GB of free space, but when I boot up PS it only shows 78gb of free space in the prefs scratch disk window?!?!!
This is before I have even created a new document.
I'm not getting the 'Scratch Disks Full' alert when working but it is DEFINITELY affecting performance. I work on large files and this didn't happen when running Catalina/PS19 - This has only happened since updating to Big Sur/PS22.3 a few weeks back.
Also what is showing is 'Purgeable space' - this seems like phantom data on my mac which I don't want!
