Hey guys,
I had this exact same problem a year ago and now forgot what I had done to fix it!
My mouse jumps around a lot, Photoshop CS 4 is slooow. This shouldn’t happen as I have 4 2.6 Gig processors, 8 gigs of ram (half of which Photoshop can use), and a GeForce 8800 Ultra. The file I’m working on is simply 3.5x2 inches at 400 DPI.
I’ve tried allocating more and less RAM, changing scratch disks and cache levels, nothing seems to work.
Any ideas? Thanks a ton
