My computer is pretty buff (1.6 G processor/64 mb graphics card/512mb ram) but I still get lag on Dragons and other graphic intensive fights. Someone suggested to up the framerate in the .ini file but when I save it and run the game, the game changes the value back to what it was before. Is anyone else having this problem or does anyone have better suggestions?

Go to your IWDII Config. and up the framerate there, I had a simialr problem except it happened when I told my characters to move, and it stopred when I uped the framerate in Config.
