Some of the pictures in preview window comes out fuzzy, I cleared the cache several times, but didn't help. Any suggestions? Fuzzy pictures opens up in Photoshop fine.
Photoshop version CS6 13.0.3X64
Mac OS 10.8.2
am I right?
No, you are wrong, the main difference between Bridge CS5 and CS6 is the transition from 32 bit to 64 bit, a different cache structure (again) and a few minor improvements, nothing further.
And if CS6 did not offer the quality settings it would be next to useless...
Try unchecking it.
If that doesn't help then perhaps you could describe what might be different in the psd files that appear fuzzy in preview contrasted with the tiff that display OK in preview. Pixel dimensions? Color? Do they appear different if you display two or more in preview vs only one? .. if you display one tiff and one psd together in preview?
Two or more previews, fuzzy ones stay blured, other ones sharp. The color space, size are esentially same. If I save the fuzzy picture in tiff format, new preview becomes sharp. On the other hand not all psd files are blurred. Just couple days ago same files in preview mode were not fuzzy. So something must happened since then. As far as I can tell, I did not make any changes either in the files, or bridge preferences.
Two or more previews, fuzzy ones stay blured, other ones sharp.
Just for experiment, try select a fuzzy thumb and with right mouse click choose 'purge cache for selection' and see if this helps.
Otherwise can you add a screenshot of the problem to clarify more?
