It seems like photoshop's performance and efficiency has tanked after the 24.5 or 24.6 update. I'm currently using 24.7 and still having problems.
I am a professional digital artist and I regularly work on pretty hefty files (lots of layers, clipping masks, some text, layer styles, brushes with directional properties, etc.) and for most of the last 7 years photoshop has been able to do the job on my computer without much fuss. However, recently it has started to lag after any significant amount of time working on a hefty file. I noticed that in fact my whole computer would lag, and upon checking task manager, that photoshop was using almost all available memory. In the two previous versions photoshop would just crash, whereas now it just lags out my computer to the point of being unusable until I quit the program and then end task in task manager (rather than waiting the weirdly long amount of time it takes for the tasks to truly end on their own).
I would just like to continue working as I have been without issue. I'm not sure if it's some new preference that was added, a bug in the new versions, or if these new versions are coinciding with my RAM cards deciding to die on their own (I hope that's not the case). In any case, I would appreciate any help.
I'm sure anyone willing to help will need me to post some text files or system files, so just let me know what you need and I'll try and figure out how to do it.
