I just downloaded the Demo of Call of Duty 4 (hopefully i'll be getting the real one for Christmas) and i'm having trouble with the rpg. About 80% of the time when I fire it the rocket either goes too high to the sides or just hits the building 10 feet below the window I was trying to shoot. Is the Rpg naturally like this or am I somehow doing it wrong because in all the walkthroughs I watch it just goes in a perfect straight line. Firing while crouching or prone doesn't help either.
