Found a solution, to cripple IWnet and bring Dedicated back!
Well im telling this because not many people know that it is possible, first of all you use mp_config method on this site to get 10 bars and a precise bandwidth, so you can see who is host. Second, you install the currenlty open for public free beta: NetLimiter 3 Beta. If you have a very good pc and you see that your bandwidth is pretty high and you can see when the game has started that YOU are the host of the game, YOU CAN BASICLY BE 10 TIMES FASTER then the rest. With dedicated you dont have this problem. First of all dont limit anything, let the game start normal, while ingame and you know there are lots of people in a house, you can limit their bandwidth and kill them in a flash! :-p They will be sitting ducks. You switch to your Netlimiter panel, go to iw4mp and fix the UL limit, usually its around 16kb/s (or higher) you limit it 3/4, set it to 10kb/s in this case, click limit, it affects direct. And basicly you can kill everyone fast. This bug cannot be reproduced if it was a dedicated server. So basicly bandwidth limiting on client site can be exploited, and is basicly not a hack, just limiting bandwidth ingame
Anyway i post this because this is a way to get dedicated back if we push this hard enough to IW!
Hope to hear your thoughts and responses on this, ill post a screenshot to prove tomorrow
