the game is much better with more memory? or all depends of the graphic card??? for example i can not play with 3d grass...with more memory it is possible???

I would say get a better graphic card first.

What kind do you have right now?

Download a program called 'game accelerator'. It boosts the dedication of your hardware to the game so it runs better. Should solve the problem. Along with this, try playing on the lowest/ lower resolution and do not have anything running in the background (internet explorer, office, fireworks anything). Norton will kill your computer so make sure that is not running and disconnect from the internet so you get no virus threats.

thanks musama, where can i get that program???
