Have CS4 Updated to 11.01 on XP.
I am still having BIG speed and performance issues with Photoshop and painting with Large 200 pixel, soft edge, low opacity brushes 3-9% opacity. I do retouching and I often have to wait 1 to 2 seconds for each application of the brush to finish. If I draw a line with 7 or 8 short strokes...then my machine may STOP for 10-20 seconds while photoshop finishes up painting the line...brush tip by brush tip. I can see the single brush applications and then happen every 1-2 seconds. Cant do anything else with the brush till the stroke finishes.
Here is what ive tried:
Updated Photoshop to 11.01, P4 Machine 3 Gigs Processor, 4 Gigs Ram, 10,000 rpm C:Drive for Program, SATA scratch disk with 170gb free, 55% photoshop memory utilization, History states 20, cache at all kinds of settings to try to fix, Have an Nvidia GForce 7600 GS video card with 500 meg on board and recent drivers. tried open Gl and Not GL, Cleaned Preferences file.
I have had this issue with CS4 from Day One. My CS3 works beautifully.
Any ideas or helpful places to look? Could it be the agp area? Any way to test system?
Thanks
