Ever since I've jumped back into the servers a couple weeks ago I've been experiencing this very odd, yet consistent lag, regardless of my ping in the server. Anyone who has been driven by me has certainly noticed this. It usually happens like this: Every minute and a half or so, I will start moving at about 1.5x times the normal speed, lurching forward at a faster pace than a hog usually goes for roughly 5-7 seconds. This happens across every map and every server that I go into, whether I'm driving or not, and regardless of who may or may not be in the server as well.
I've played around with the settings for a week or so, but nothing seems to be changing it in a significant way. If this isn't an easy fix, it's not too big of an issue (it hasn't seriously affected my gameplay, though gunning has become much easier for me to deal with than driving), but I would prefer that it be solved. Any information on what could be happening is welcome.
