Yes. Open your GOF2 folder and find the engine.ini. It opens with notepad. At the top make sure full_screen = 1. Then below that set your screen resolution. X = the larger number of your screen resolution and Y = the smaller number.
My screen resolution is 1920 X 1080 so X = 1920 and Y = 1080. Save and you are done.
