Left 4 Dead Crash Fix : Lag, Freeze, Sound Loop

left-4-dead

IMO Left 4 Dead is one of the best shooting game ever created for PC platform. Being a big fan of this game I would love to play this all night long, but I have often face with problems such as the game freezing every 1-2 hours I play, sound loops and even lagging. So for those Left 4 Dead fans if you are facing the same problems then here’s a post that might give you some help.

Freeze Fixes

open the console and enter “mat_queue_mode 0″ (minus the quotes). It will help to disable multi-core for the game

Lag Fixes

At the main menu hit your console key (Default ~) Then in the console type in “openserverbrowser” (without the “s) and hit enter go to the custom tab and re-fresh all and join a server that pings less than 100 to you.
At the main menu hit your console key (Default ~) Then in the console type in sv_search_max_ping 100 (default is 250) Should make Launching games from the Lobby a bit less painful.

Sound Loop Fixes

Try Setting shader detail to medium. (Graphics setting) ~ From DodgeRodge
Try Setting sound quality to medium.
Check to make sure you only have one sound device installed
start > run > dxdiag > If you have more then 1 Sound tab, uninstall the one that isn’t your sound card.
