In the game options you can try to dumb down some of the graphics settings. Change these settings under the basic tab if you haven't already.
Flash Quality: LOW
Reflections: OFF
Putting Grid: OFF
Friend/Invitation Alert: AUDIO OFF
Then, under the Advanced game options, try these:
Avatar Rotations: OFF
Background Loading: OFF
It's not going to make a huge difference, but it should help out a little. Good luck!
