I am running Photoshop CS on Windows XP using 512MB RAM. I would like to know what is the best amount of memory to set 'Memory & Image Cache' in the 'Preferences' menu to? Also, what is the ideal setting for 1024MB RAM?
I generally open files around 10MB in size on the hard drive. However, when they are opened in Photoshop CS, the 'Scratch Size' in the status bar shows 'Scr: 713.3M/270M'! Indicating that photoshop has bloated the file to 713MB for editing. Shocking or am I interpretting this wrong?
