riddleofsteel: Yes, I have already been able to switch the resolution via config.div but it crushes the picture to a smaller square in the middle of my screen. It doesn't even fill my monitor's screen. That's why this is so peculiar, if it was really 1600x1200 it would just fill my monitor and it would be perfect. I am led to believe something isn't working right.
May sound strange but make sure your monitor supports that high res you have entered into the config.div. If it doesn't support the res you entered it could cause some strange results.
Not sure what OS you have but (Vista) right click the desktop, select Personalize, Display Settings. You should see a dialog with a resolution slider, if you move it all the way to the right, that should be the highest res your video card/monitor combo can support. If it is lower than what you entered into the config.div it would mean you are forcing your card/monitor to display a res it cannot support, hence the problem. That "highest" res should be what you enter into the Config.div as that would be the highest your system would support.
Make sure your config.div looks like this and that you don't have the width and height numbers reversed.
// display width
width 1600
// display height
height 1200
Make sure you have the latest video drivers.
If you can run the high res and you have the latest drivers, see if there is a "stretch" setting in your driver configuration, used sometimes to make standard graphics fit a wide screen, turn it off and try the game. Other than those suggestions, I have no further advice, sorry. . . =^ )
Edit: Just curious, what is the highest res you can run and the screen looks "normal" ??
