A Auto Update for Call Of Duty 3 went live last night. The COD3 Multiplayer team posted what this update fixes.
This update addresses many of the Ranked and Player Match issues that we've discussed over the last few weeks. While we've made a number of enhancements, the most significant improvement is that Ranked Matches join lobbies much faster through both Custom and Quick Match. Player Matches through Quick Match will now query a higher number of games before attempting to join, thus returning a better variety and better quality for the player.
Additionally, we've added some gameplay, HUD and options enhancements.
For example, brightness settings will be saved across both single-player and multiplayer; players will be able to instantly punish medics who maliciously team kill and revive continuously; Auto Team Balance will remain turned on after multiple map rotations, ensuring that each team always has an equal number of players; and players will be able to select either Axis or Allies in Ranked Battle games.
These enhancements will create a more streamlined gameplay experience; however, please be aware that online play is always complicated by players with non-optimal router and connection settings – don't hesitate to refer to Xbox Live's "best practices" for router configurations, as it will prove helpful.
