HOW-TO : Block a server for one game.
1) Have an enough old computer (i have fps 20 and no shaders)
2) Download
this game
3) Run toribash.
4) While you are on a server run the game but in WINDOWED mode.
5) Fps toribash = 0 (just watch the task bar, if the fps isn't changing at all you succeed)
Now you are blocking the server! When it will be your turn the server will wait for you and wait and wait.
1) You are not pinged because internet is working
2) But it won't start because you have fps = 0
I tested it and it nearly worked perfectly.
But when the other player quit you are forced to play. (because the game start instantly and fps = 1)
Still this is a bug because the server can stay blocked for a looong time.
