From Chris' FPS configs

// ----------------------------------------------------------------------------
// Net settings
// ----------------------------------------------------------------------------
// Whilst net settings perhaps aren't an integral part of an FPS config, they
// are a fact of life in competitive TF2, and as such, they are included here.
//
// A common question I am asked -- what defines whether a good connection is
// good or bad? Mostly personal preference. If you're not willing to make the
// choice, try both and see which is better for you.
//
// Generally, meeting both of the following conditions would classify it as a
// good connection:
//
// - Ping of <80 to the average server you join
// - Generally no/negligible choke/loss (can be checked with `net_graph')
//
// There's some pretty good documentation on this here:
// http://developer.valvesoftware.com/wiki/Source_Multiplayer_Networking
//
// Uncomment (remove the `//' from) one of the groups if you want to use them.

edit:removed the lan settings

attaboy

re-PSA: DO NOT USE THOSE LAN SETTINGS. THEY ARE BROKEN. Chris removed them from recent versions of his configs because they don't work the way they were expected to and absolutely positively ruin hit registration. His "good connection" settings are the best settings you can possibly get for a LAN connection.

lol... I used those lan settings my first lan and the reg was the worst I have ever experienced. i mostly just assumed it was all mental

cl_lagcompensation 0

justin reminded everyone of that
