Photoshop CC is running slower since yosemite update, is anyone else having the same issue? It's particularly laggy with the stamp and brush tools...taking a second or so to update. I have 48GB of ram so memory isn't the issue.
Could be an issue with Yosemite (there have been many reports of such). Revert to the previous OS and see if the problems persist.
I didn't do the sensible thing and partition my drive, now no longer have access to mavericks ( why doesn't Apple make it available as a download for instances like mine ? ) I waited for the final version of Yosemite and assumed it had been fully tested with Ps. Is there a way to get back to Mavericks? Can I purchase Mavericks from somewhere...I'm upset as a slow Ps adds hours to my working week.
