    Big Brush Runs Real Slow - How to Speed Up

    suzzie12 Community Member

      In CS4, when I try to paint on an 8x10 300dpi portrait with a large, soft, low opacity brush...the appliction of the brush sometimes runs 2-5 seconds delayed  behind where I am.  I put down a few dabs and its OK... but then... when I put down 10 dabs in succession...then there is a few seconds delay. This same thing Does NOT happen in CS3.

       

       

      Im trying really hard to fix this by optimizing all I can.  I have CS4 on Win XP SP3, and a 3 gig CPU, 4 Gigs of Ram, and an Adobe recommended Gforce 9600  512mb video Card set for open GL2.

       

      Ive set the preferences to 55% of memory for photoshop with 2 gigs of free memory, I set the history states to 20 and tried adjusting cache levels from 4 to 6, and I have a separate SATA scratch disk with 32 gigs free.  AND, Ive upgraded to version 11.01

       

      I dont get it.

       

      Why are my brushes taking so long in CS4 when they run perfectly in CS3?

       

      Any more ideas or help??  What am I missing??

       

      Thanks
