There have been quite a few reports of Photoshop CS2 slow re-drawing and slugishness issues on some systems. Apparently it's because of some graphics cards drivers not implementing the 2D APIs properly. The problem is most obvious as a slow or stuttering movement of the cursor when the 'Info' pallete is selected and the CPU usage sometimes reaching %100.
You should be able to get CS2 to perform as good as or better than CS by reducing the acceleration of your graphics card slightly. Close Photoshop CS2 and then (for Windows XP Pro - may be a slightly different way to access the settings for other versions of Windows) right-click on the Desktop. Select 'Properties' and then the 'Settings' tab. Select 'Advanced' and then 'Troubleshoot' and reduce the 'Hardware acceleration' slider-setting by one notch. Then answer 'OK' to close the panels.
(Desktop>Properties>Settings>Advanced>Troubleshoot >Hardware acceleration)
Now try opening Photoshop CS2.
Hopefully the problem will be fixed properly when the graphics card manufacturers release new drivers.
