If your computer's performance is poor enough to cause you to jump around on the server, you should probably upgrade before registering for other multiplayer races. "Minimum requirements" for most games does not take into account the ability for the computer to also handle stable Internet connectivity while trying to maintain framerate in game, so likely you are a giant, unpredictable road hazard in these cases.

And even if this magical performance enhancing program you installed gets AC to stop the connection warping you were experiencing, the midpack is always where the most incidents occur. As you said: it'll take practice. Good luck!
