I've noticed that my Graphics options are reset every time I log in. I'm not sure if you were able to run with good FPS on the default settings, but I was/am not, I have to set my graphics settings to get a usable framerate every time I log in. Once I return to settings that are close to what they were before, my framerate is good.
As a positive point for me, I've learned what that I was taking more away from my graphics than I needed to, so it looks overall better... and I now have my graphics settings memorized.
