My dad up graded to the 4.5 and gave me his old 3. I used it alot on his computer but on mine it doesn't fly the same. It seems like reaction time is slow and control is alot harder. Could this be a video card not being as good as the one he was using or is there something else I need to look at. My computer is new and seems faster than the one he was useing so I don't think it is the computer it self.
