Those fixes never worked. It's part of the game used to give people with higher pings a better chance. The game basically tries to even out the pings but the people with better pings seem to suffer. Friends of mine still complain about it and rage when they get shot by guys bending bullets around corners.
Yea rubberbanding sucks, that might be why, I had a 30mpbs connection, dropped great scores, was probably getting lag compensated. I still don't understand though, many people I know have fiber optic and get even better connection, are they throttling down their upload? How do you do that?
