Dark sectorDark sector crashed on me everytime I tried to change the resolution from the default 800X600 (Yes this game does not even try to behave (configure) itself in front of my 4890 OC ) to 1680*1050.
Thye solution is simple open the game’s installation folder, open the subfolder called Configs, double click the file DS.cfg, then click select a program to open it. From the list choose “Wordpad” and hit ok
The configuration file is now open, just modify the following two lines to match the your preferred resolution
save and exit wordpad
Congratulations, now you can play the hi-res version that you deserve.
