Photoshop CS6: slow performance on Mac Pro, Mountain Lion.

On my mac pro (8 core radeon 5870), when moving a layer that has text above it that has a drop shadow, the process is unusably slow. I really do mean unusable. Hiding the text layer or removing the layer effects helps. It is however still slow for a machine like that. I have tried all the combinations of GPU options etc and the file is a relatively small one.

CS6 should fly on the mac pro, but instead it is slow to the point I have to work on my macbook air at the moment. This is on Mountain Lion (as is the macbook air which seems fine).

Thank you,
Richard.

Have you restarted Photoshop each time?
Have you tried turning off »Use Graphics Processor« in the Performance Preferences altogether?

Other than that which of the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.) have you performed so far?

Hi Christoph, thanks for replying.

- Yes I restart PS after each tweak.
- Yes, tried turning off GPU altogether

Preferences trashed, no effect.
One thing that (very slightly) helped was setting the GPU tile size to be smaller. Made a very mild improvement.

I should note this is also happening in CS4 now, which didn't before. Although I haven't used it for a fair while so it may be the mountain lion upgrade or may not???

Thanks again,
Richard.

Yes, it has something to do with the 10.8 upgrade. But what?
You could have corrupt fonts or a corrupt OS font cache.
Or some utility, third party plugin, or another application that isn't compatible.

But based on your description, it probably has to do with fonts.

Hi Chris, thanks for the tip. I will kill and rebuild my font caches when I get a moment and try it out.
I'll post back here on how I got on.

Thanks,
Richard.

Oh I'll add that there are no plugins active (one of the first things I tried). Hopefully the cache is it!
