Canvas freezing

So a couple of days ago, my photoshop started acting up when I was drawing (which is what I do in Photoshop). 
I use a wacom tablet. 

I heard some people had the same troubles as me after the newest update, while drawing my canvas freezes. I can still pick tools, but i cant move the canvas, I can save, close down the window, start it again and it works... for a while. 
I tried to just close photoshop down, and it works the same as just closing the canvvas. 

I posted help on a FB photoshop group, where i was told to try check off "Graphic processor" so i did that, and the lines are pixelated when working, its not running smooth rather laggy, and I am unable to rotate canvas.... which is kinda a big handicap for an artist. 

I turned the graphics on again, but i still cant rotate, i guess i have to restart the program. 

But the problem being, how to fix the freezing? 
A normal illustrations takes atleast 3 hours, and if I have to sit and close and open the program every 10 min, its gonna be... i just cant do that, i need a fix for this. 

Hope someone can help!
