L4D1+2 Tickrate Enabler 1.3

tickrate_enabler 1.3 by ProdigySim

  • Enables the "-tickrate" switch to be used from the command line to set the game's tickrate.
  • Patches Boomer Vomit behavior to fix an issue where vomit range scaled inversely with tickrate.
  • Removes global upper-limits on the max client data rate (was 30000), and removes the (30k) limits on rate control cvars:
    • sv_maxrate
    • sv_minrate
    • net_splitpacket_maxrate


1. Place tickrate_enabler.dll (Windows) or (Linux) in your server's addons folder.
2. Place tickrate_enabler.vdf (L4D2) or tickrate_enabler_l4d1.vdf (L4D1) in your server's addons folder.
3. Add "-tickrate <desired_tickrate>" to your server's launch parameters. e.g. -tickrate 100
4. Make sure the following convar settings are properly set in server.cfg or otherwise:

    sv_maxupdaterate 100
    sv_maxcmdrate 100
    fps_max 150 // higher than 100 recommended, as ticks calculated seems to dip otherwise.
   sv_maxrate 0 // 0 = unlimited, but you can also set this manually. Default is 30k for 30tick, use math.
   // Setting higher sv_minrate can be used to force users to use higher data rates.
   Note that fps_max and sv_maxrate are hidden variables on most scenarios.

5. Done. Enjoy 100 tick L4D2 gameplay.
