INF's lag seems to be linked to the person on the team with the worst ping. I have noticed tremendous lag when I am showing pings of 80 or so - but one other teamate has a ping of 400. If I am on a team and everyone has ping rates below 175 however the game will rock (especially if the other team has a few 400 pingers ) I think it has to due with the need to keep track of all the other players locations 'cause when you die you can look through any team-mate's view. Maybe if they disabled this switching through "team-mate" view and just use normal ghost view the ping rate would have less impact, (Chances are not likely as this would be an engine hack rather than a mod hack <DANGIT!>)
