Allows changing the tickrate of the server at runtime. Thanks to ficool2 for discovering this method.
Note
As of now, this only supports Team Fortress 2 on Linux.
Anyone is free to contribute gamedata and functionality for other games and platforms, but I probably won't do it myself.
The plugin defines a console command sm_tickrate and a console variable sm_interval_per_tick. The convar default is set to the game's default tick interval.
You need to call or set either of these before level change for it to have any effect.
It is safe to do so at any time during or before the OnMapEnd forward, as the new tickrate will only be applied on level change.
Calling sm_tickrate with a value of 0 will return the server to the default tickrate. Alternatively, sm_interval_per_tick can also be reset to its default value using sm_resetcvar.
If you need the tickrate to be applied on server start or persist throughout the server's lifetime, the -tickrate launch parameter can be used.
