ATI 13.1 - Photoshop laggy/slow performance

Question

So yesterday i chosed to update from my 2 year old display driver 10.9 to 13.1 a big jump, but it seems like my photoshop has gone way down in perfomance compared to the other driver
so i tried ti disable "Graphic Processor" and it kinda solved it, but when i have the option enabled my ps feels terrible when i drag stuff around it laggs and feel slow, tried with all kind Advanced settings > Drawing
Basic - Normal - Advanced same performance with all of them, but slightly better the lower i set it
i hope anyone can give me a solution so i can keep going with my creative art adventure
I dont know if my system spec is usefull, since it run smoothly with an old driver which means my setup should be able to handle it.

I suspect that something else is at play, then.  I have a 7850, before that a 5670, and neither could be called "laggy and slow" with Photoshop CS6.
But it's good that you rolled back to 12.8.  There are at least 3 well-known problems with 13.1, including colors blacking out, missing lighting rendering in 3D, and even failures for the monitor power-down screen saving to work properly.
I wonder whether your Photoshop preferences might have become corrupted with all the system changes.  You *could* try a general preferences reset to defaults.  This involves pressing and holding Control - Shift - Alt immediately after cold-starting Photoshop.  You have to be quick, and if you're quick enough Photoshop will prompt you to confirm deletion of your current prefs.  Of course, this means you'll need to re-make any preferences changes from default you've chosen to make over time.
What's a specific operation you're finding to be laggy?  You mention dragging stuff around...  What size document (pixel counts, bit depth), howw many layers, what kinds of layers, how laggy (xx seconds to drag from one side of the document to the other, etc.)?
