First of all, get your facts straight before making any accusations about bad netcode etc, here's the real deal:

there is NOTHING wrong with the netcode, its actually quite excellent. BUT, in the demo there is a SERVER - bug, that causes all those "warning connection problem" and making people's ping go up to 1023. Also there is a problem in the client that can cause the server to go fubar.

This has all been adressed in the final version.

Also, the crash-bug, ie; you get a black screen and it crashes back to the desktop with an error log saying "invalid videomode specified"

Solution: If you have ANY sort of Nvidia REFRESHRATE-FIX,/Refresh Force etc remove it, or move back to 60hz for the resolution that you play with, there's a bug with those sort of programs that causes the crash. This has of course also been adressed. //Tony
