I have a desktop machine and it is been installed with Windows 7. ALso I have installed Fallout 3 game to the system. The problem is that I am not able to play the game well. I have no idea why is this happening? It has really caused a huge problem for me now. It gets crashed when I execute it. I used the patch but ffdshow shows up nothing. I have no idea for the thing. Hope to get a better result out here.
