Here are a few pointers I have found to ensure optimal performance, at least until the netcode gets polished a bit. -Make sure you download 1.04f, this is a must! -Don't play games with anyone whose ping is greater than 200, if there are some high ping players in your room, politely tell them what the situation is, and then boot them. -If you are behind a NAT router, don't try to host right now. -Don't play games with any more than 4 players or so, too many players right now will cause the game to hang in the transition from the staging window to the setup window. One day we will have likely have 24 player matches without hiccup, but for now, keep things at 3-4 players. In fact, I have found that 1 vs 1 with a bunch of AIs is probably your best bet, but if you have to have more people, keep them at 3-4. -Play on smaller maps, to ensure optimal performance and more lively games with fewer people. If you do all these things, you should look forward to some extremely fun and exciting MP games while things get polished up a bit on Firaxis' front.
