I run a Intel quad core 6600 with 3.2 gigs of system ram and an Nvidia 8800 Ultra 768 megs of ram. Running on Vista 32 ultimate. I believe my machine is within Adobe's specs to run the program, yet I am experiencing the slowness like others. I have the latest video drivers, but I get a little bit better performance with the advanced/3d performance taken off in the preferences. CS3 runs as smooth as ever however. I am seeing very strange behavior leading me to suspect I may have a bad install though:
I can't even just "open" something, it's greyed out, I have to choose "open recent" and then "clear recent" to get the "open" option to appear.
Changes made to a photo or a project require that I either zoom in or out or resize via mouse drag to see the change.
Example: Once I go though the whole "open fiasco" and finally get a photo open, some strange things happen......I sometimes don't get a thumbnail in the channel/layers section. If I do get a thumbnail and I go to alter the photo like say levels or curves, the change won't happen until I either zoom or resize. Although I can see the change happen in the thumbnail if it's there.
Also, when I make a change, most of the time the "undo" is greyed out, which is weird. I can still do the "undo" via keyboard command though, but again, I have to zoom or resize to see the change.
Example: I will open a photo and have the channels/layer thumbnail there. Then switching to lab color I sometimes will lose the thumbnails, then after picking the lightness channel and bringing up unsharp mask, the display will just be checkerboarded and only when I hit the zoom percentage just under the display area in unsharp mask window will the picture come up. Then when I hit ok to that and it goes back to the main, I lose the thumbnails for RGB and Lightness, yet color channels A+B thumbnails are still there? Sometimes I will see the sharpen change, sometimes I have to do the resize/zoom thing. Then again, I'm still not out of the woods. I have to switch back to RGB now and guess what, all of a sudden "mode" is now greyed out?
Sorry for the long post, but this is very, very bizzare behavior and I'm wondering if anybody is seeing this? At this time I'm starting to think I have a bad install, even though no errors or messages came up in during the install other than that it was successful and finished. Also, I do not get any crashes or codes, so it seems stable from that point of view for me.
