I wonder if there is a way to speed up CS when it’s time to open a large .Tiff image. The slowdown is probably due to the image thumbnail attempt showed in the Open file window.

Slow on very big tiff files. Appears to only response after each thumbnail is loaded. My files are over 100MB and that’s a long wait between each thumbnail.
Can’t you program the thumbnail loading in a background thread so the event loop is not blocked?
Same issue here (I think). The image previews in the File>Open dialog box take ages to display with large PSD files. This happens in both XP and 2k. Oddly, tiffs don’t seem to exhibit this behavior.
I guess I have to add to this thread, too. I just started working on a project that uses some TIFFs that are over 200 megs. I need to scale them down for the project.
I’ve had to go back to 7.0 to get a couple of them to open because the file>open dialog box chokes on them as soon as I select them.
Bob, if you are comfortable looking in the registry, can you tell what "Icon Bits" is set to, it should be under HKEY_CLASSES_ROOT\CLSID\{0B6DC6EE-C4FD-11d1-819A-00C04FB69B4 D}\MiscStatus and HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{0B6DC6EE-C4FD-11d 1-819A-00C04FB69 B4D}\MiscStatus
Bob, I have created a directory with some 100 and 200 meg images (all of the new $20, just for the heck of it) and except for the initial display of the explorer dialog when the machine cranked for about 30 seconds creating the thumbs.db file, I can’t replicate your problem. Sorry I couldn’t help but I’m fairly confident your problem is somehow connected to psicon.dll – but with icon bits set to 1 you should have got preview images when placing the files on your desktop and they should have taken forever to generate in an explorer view, regardless of the view settings.
Is your FileBrowser preference currently set to generate high quality previews? If so, try removing that preference to see if it allows you to open the files while the preview is being generated.
And for reference here’s the rest of the settings:
Do not process files larger than is set to 50 megs Display __ most recent files is set to 10 Custom thumbnail size is set to 256 px wide Allow background processing is off Render vector files is on Parse XMP meta data from non-image files is off Keep sidecar files with Master files is on.
I have been also trying to get at the cause of the File|Open dialog delay. I’ve tried all sorts of registry ediiting but nothing I did affected it all. Two things have been more or less successful, however: 1. Uninstalled CS and re-installed without a previous PS7 install, this makes a noticeable difference 2. Unchecking the high-quality previews makes a noticeable difference, and with both of these I seem to avoid the temporary lockup that occurs while the preview is being generated. 3. It is still not as peppy as PS7 moving around the dialog box. 4. Do a File|Open in Imageready and you will see what the goal is – there is no image preview under the dialog window and the file size of the contents of the window is completely immaterial
