CSB Speedhack Detection watches the one thing a client-side speedhack cannot hide: it makes the client send far more usercmds per second than the engine should ever process. The plugin counts usercmds from the CmdStart forward and, once a second, compares each player's rate to a configurable ceiling. A single spike is ignored; a sustained rate over several strikes is treated as a hack.
csb_speed_maxcmds adds a strike; a clean second removes one.csb_speed_strikes logs the player and, with csb_speed_action 1, kicks them.The default ceiling of 350 usercmds/s sits well above a legitimate 250 fps player but far below what a speedhack produces. Raise it if your community runs uncapped high-fps configs.
