So what I've been able to play of the game is fun, but unfortunately (I think because I'm running it on a fairly old computer) I've had some trouble getting it to run at full blast. It works fine if I tone the settings down, but they all reset anytime I start the game. Has anyone been able to find a way, either within the game interface or in the program files, to easily set the default graphical settings differently? Thanks.

It's under options in the game. Mine keep track.
