I have Photoshop 4, & I don't know about later versions, but it has the
peculiarity that no matter how much memory I give it (within the
limitations of the (soon-to-be-upgraded) 128 MB on my G3 DT/OS 8.6), even
the tiniest brushstroke will cause the disk to churn a bit.
I was told on 1 of the lem-lists, I forget by whom now, that you can create
a small (4 meg will do) RAM disk, & specify it as your primary scratch disk
in the Pshop preferences. This will cause Pshop to write all the little
undos to that RAM disk. (Of course you must specify a secondary drive to
write the bigger changes to; all in all you must have enough space to hold
Pshop's memory partition, as in earlier versions.)
This seems to work! Now all my brushstrokes (at least) are silent --
filtered areas are another thing. At least it saves wear & tear on the
hard drive. I don't know how it would work under X.
