TechDudeYou know the thousands of times you've seen the STV drop in the last 90 seconds of a game?
Setting tv_delaymapchange to 1 on the server stops this from happening.
Except it doesn't work. AFAIK it only delays map changes due to timelimit, so it's nice for pubs with mapcycles. It won't delay manual map changes or even hitting timelimit in tournament mode.
Like f_blue says, use F2's plugin or TFTrue for proper 90s delay (that can still be overruled by retarded people with RCON, which is what happened with the cast tonight).
