Server Install

• Step 1: A clean L4D2 Dedicated Server.

• Step 2: Choose "Windows Server files" or "Linux Server files" (depending on the operating system of your server), and place the files provided in the correct folder.

• Step 3: Adjust your server_rates.cfg and l4d2_resolve_collision.cfg to match your server tickrate accordingly.

  • For 100 Tickrate, you'd want these settings:

     // server_rates.cfg
     
     sm_cvar sv_minrate 				"100000" 	// tickrate * 1000
     sm_cvar sv_maxrate 				"100000" 	// tickrate * 1000
     sm_cvar sv_minupdaterate 		"101"	 	// tickrate +1
     sm_cvar sv_maxupdaterate 		"101"		// tickrate +1
     sm_cvar sv_mincmdrate 			"101"		// tickrate +1
     sm_cvar sv_maxcmdrate 			"101"		// tickrate +1
     sm_cvar rate					"100000" 	// tickrate * 1000
     sm_cvar net_splitpacket_maxrate "50000" 	// (tickrate÷2) * 1000
     sm_cvar fps_max					"0"

     // l4d2_resolve_collision.cfg
    
     // Multiplier of commons collision force
     // 30tick = 0.65, 60tick = 0.15, 100tick = 0.05
     z_resolve_zombie_collision_multiplier "0.05"

• Step 4: Change the Launch Parameters.

   -console -game left4dead2 -port 27016 +log on +map c2m1_highway +exec server +sv_lan 0 -tickrate 100 -maxplayers 32
