I'm running 64bit CS6 and have 24GB of ram. GTX 660ti. This shouldnt be a problem and has not been. My psd which is almost 500MB usually takes 30-60 seconds to open and once i am in it works fine. It just took me a good 5-10 minutes to open the psd. The efficiency is at 19%* and i dont know what that asterisk means. I allocated 22GB of ram to it, 8 cache levels and such and it's still being really slow. Should I try reinstalling? This is very cumborsome and would like to fix this problem asap.
this also happened randomly. The program wasn't even closed. My brushes reset, too. I even tried rebooting, and nothing.
also, photoshop now uses up to like 20gb of my ram automically without any files open in the program. Before it was about 6-9gb.
This might help temporarily:
What are your complete Performance Preferences?
Are Photoshop and OS fully updated and have you performed 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.)?
I did that ctrl+alt+shift thing and my preferences are all max. well theyre at default now. still taking forever to load up my file, though. my os is up to date and as is photoshop cs6 64bit.
edit: right now my cache level is at 4 but im not sure what to set it to. the file it has many many layers. but is also big.
the dimensions are 3800x3800 pixels and a resolution of 72

If your efficiency is down that says your document requires more RAM than you have. That's reinforced by the performance degradation that you're seeing.
You may feel you have a big system but you've either done something or accumulated some kind of corruption in your document that requires more RAM than you have.
Consider changing the way you use Photoshop so as not to accumulate so many layers.
