O.K., this is weird. Noticed recently that Photoshop is sluggish. I started noticing this immediately after installing a trial of CS6. Didn't go with the trial. Things worked well enough until last night when I was working on very large files. Two 2.5 GB scans, stitched in Photoshop. Things slowed to a crawl. Painful. Thought it must just be the size of the files but by the third one I'd had enough, fantasies of a $12,000 Mac Pro system dancing in my head.

Tried a few things and then looked at Preferences. Saw that 17 GB was allocated to Photoshop out of 20. What? I have 32 GB in the machine. Blinked and realized it said 1.7 out of 2.0 GB. Googled and realized that Photoshop was opening in 32-bit mode. What the heck? I didn't even know how to open it in 32-bit mode until I googled.

Ditto on my laptop. Also installed CS6 there.

Did CS6 attempt to cripple my copy of CS5 to make it look better during the trial period???
