In PS CS my brush tool has become so slow that it may take a minute or more to paint down a single stroke. The slow performance depends upon the file size, but it is slow, slow, slow. No other tool has this problem.
I’m using Photoshop CS on a Mac G4 running OS 10.2.8. It’s a dual processor with 2 GB Ram. The problem occurs with the mouse and the Wacom tablet.

The histogram palette is closed. I turned off "spacing" in the brush palette and performance improved a little bit. Performance is still terrible, though.
I was having the same problem, also other tools were operating sluggishly, until I reduced the memory allocation from 70% to 60%. I have 1G RAM in a G5, so maybe your memory max is different. Got the idea from a post on another subject.
Yes, I’m working in very large 16 bit images. But, 8 bit, small files still exhibit the same probelm; only not as badly.
There is plenty of HD space and lots of memory (2 GB total) available. I’m allocating 60% of 2 GB for PS use.
Responding to Ann’s comment. Yes, I’m painting with disconnected dots when I move the brush at greater than snail speed.
Ann also mentioned an old tablet driver problem, but the problem manifested itself without a change in tablet drivers or software upgrade. It just started becoming more of a problem over time. But, I will upgrade drivers if there’s a newer one and report back.
