This used to work before the newest patch, i'm talking about simply changing the resolution of the game in the text document "settings.ini" to 640x480 but that doesn't work with the newest patch because it automatically changes it back to 1024*768 well i found a little solution that some people might find useful and others will say "BAH! CRAP I KNEW THIS".
