If you also have had enough of being smacked down, fire mushy peas out of your shotgun, stickied and slashed just because your opponent see's you on-screen half a second before you see him..... here is the answer, read this thread: Bungie thread Join the Clan: DOT Realm No screamers, or mouthy 10 year old yanks allowed!! also interesting: lag and latency for dummies bring on regionalised servers or some sort latency balancing check your latency by Xbox dashboard - Settings - Network -Connect - Press "Y" on your pad - read "L" for latency also found this on bungie.net it cam from someone at bungie who wrote a lot of the network code: So the solution to your problem is that the people in your party with good connections (384kbps upstream or better) should do two things - make sure that their routers are configured properly (there is more information on the Xbox website about this), and build up a good hosting record by playing in lots of games, either ranked or arranged games, with lots of players. If you want to make sure that a specific person builds up their host record, you can take advantage of the way that the networking model works and ensure that they build up a good background. Here's how to do it. 1. Select your host! 2. Make sure they have a good network connection. I personally have 640k SDSL but anything 384k or above should be sufficient. Cable modems are very variable and may be good but may also be sub-par. 3. Make sure they have a correctly configured router. Xbox.com has more information about this. 4. Make sure they have a good record of playing games to completion and not quitting out early. 5. Have them create a party of one and start a custom game. This will ensure that when the game starts they are the only person on the game, therefore they are the host. 6. Get 12-15 of your friends and join in progress to this game. Start playing. 7. Watch the network status indicators (on the scoreboard if you press BACK). They should start out at 1-2 bars and grow over time as the game adjusts the available bandwidth and discovers that your host has enough to handle the game. 8. Once the network indicators show that everyone is at full strength with 6 bars (or if the game has maxed out the available bandwidth and is not growing any further), you can end the game. Make sure the game lasts at least 5 minutes or it will not be recorded as a successful bandwidth measurement. 9. Have everyone leave the party and go back to stage 5. If you repeat this procedure for 5-10 games, then you should have a lot of good bandwidth measurements for your host. This post just presents a recipe for how you can accelerate that process. It wouldn't be necessary except for the fact that we lost the bandwidth records. But it should let you work around this temporary problem.
