Graphics do not fill entire screen

[jondecker76]

I want to get into playing the demo (If i like it I will purchase it) but first I want it to run correctly. No matter which resolution I choose, it only fills a part of my screen. For example, selecting 640x480 will cause the video to display on only 640 pixels by 480 pixels of the entire screen area instead of filling the entire screen (my monitors native resolution is 1680x1050). I am also running on Linux (Ubuntu 7.04) with an NVidia 6200FX card with the latest drivers.

Can anyone help me? I don't mind manually editing configuration files either...

thanks,

Jon
