autoexec.cfg

// Place this file (autoexec.cfg) into your Left 4 Dead 2 CFG folder,
// similar to the path below:
//
// <install folder>\Steam\SteamApps\common\left 4 dead 2\left4dead2\cfg\
//
// For an additional performance boost, customize your command line
// launch options for Left 4 Dead 2 in Steam before starting the game
//
// Setting Launch Options
//
// 1. Go to "My Games" in Steam
// 2. Right click "Left 4 Dead 2" and select "Properties"
// 3. Select "Set launch options..." and enter the following:
//
//    -w 1680 -console -refresh 120 -heapsize 1572864 -high -noforcemaccel -noforcemparms -noipx -nojoy
//
// -w 1680            Sets resolution to 1680x1050; for 16:10 widescreen monitors - tweak as necessary
// -console           Enables developer console; so you can press ~ to enter commands
// -novid             Disables the intro movie, speeds up game on start-up (doesn't seem to work in L4D2 yet though)
// -refresh 120       Forces 120hz/120fps refresh rate on monitor (if available)
// -heapsize 1572864  Allocates RAM for the game; see table below for calculating optimal values
// -high              Forces high CPU priority
// -noforcemaccel     Forces desktop mouse acceleration settings
// -noforcemparms     Forces desktop mouse button configuration
// -noipx             Disables IPX network detection, local LAN (slight boot time improvement; you may need to remove this for LAN parties)
// -nojoy             Disables detection of 3rd party gamepads and controllers (slight boot time improvement)
//
// Heapsize Setting
//
// Modify the heapsize command to allocate 50% of the RAM you have
// in your computer (NOT video card memory!) in bytes.
//
// Formula = RAM (in GB) * 1024 * 1024 / 2
//         1GB    -heapsize 524288
//         2GB    -heapsize 1048576
//         3GB+   -heapsize 1572864
//
// Since L4D2 is a 32-bit application it is believed to be capped at
// a maximum of 3GB of RAM. Setting heapsize to a value beyond this
// may crash the game.
//

// http://www.nextlevelgamer.com/counter-strike-source-launch-options/
//
// Removal Instructions:
//
// Don't like the config? Simply delete autoexec.cfg and config.cfg
// from Steam\SteamApps\common\left 4 dead 2\left4dead2\cfg\
// Depending on your Steam Cloud settings, you may need to redefine
// your key bindings and personal preferences after this.
//
// Note: - Brightness too high? Set mat_monitorgamma_tv_enabled to 0
//       - Prefer default crosshair? Set cl_crosshair_dynamic 1
