Kaizen’s Left 4 Dead 2 Config Version 1.1 – Kaizen_L4D2_cfg_v11.zip Download

So I love playing Left 4 Dead 2, especially multi-player with friends, it’s just a really fun game – it’s pretty old now (it was released in 2009) but it’s till looks pretty good and is really fun to play and not too expensive (Steam link).

I found this config that makes the fast paced game a little easier to handle, it boosts FPS, uses a better cursor, brightens things up a bit, improves accuracy through network settings and a few other tweaks.

Overall it does make my game better, and recently I wanted to install it on the office computer but had immense problems finding it to download. So when I eventually did find it, I thought I’d better post it here without all the spam, ads and malware for people to get hold of it easier.

So yah, here is Kaizen’s Left 4 Dead 2 cfg version 1.1 – Last updated Nov. 21, 2009

Steam Launch Options

For an additional performance boost, customize your command line launch options for Left 4 Dead 2 in Steam before starting the game.

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:

This is for a 24.5″ Dell monitor 1920×1200 resolution, so find the correct resolution for your monitor to add to the -w option.

Launch Options Explained

-w 1680 Sets resolution to 1680×1050; 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.
