Hey guys,
Ii don't know about you, but I suffer from crashes in game while playing the Left 4 Dead Demo. Sometimes they are frequent and sometimes they are not. I searched the internet to find this is not an uncommon problem. Anyway I found a LEFT 4 DEAD DEMO CRASH FIX! It is as follows.

1) Enable the Console in options. Open the console and type:

mat_queue_mode 0

This tells the game to only use a single core of the processor, there is a bug in the demo that doesn't like dual core.

2) In the Video Options change "Fullscreen" to "Windowed (No Borders)"

If you run at full resolution this will look exactly the same as fullscreen, no worries.


I honestly don't know how number 2 helps the issue, but it does. I've tested every combination of these two fixes and they BOTH need to be done in order to get consistent non crashing.

PLEASE let me know if you have even ran into the crashing issue and if this helps, good luck. :)
 
I run dual core E8500 and in windowed with no border. Game runs just fine.
 
Yeah each time I've gone on L4D the game just smoothly crashes to desktop. No freezing, no stutter, just BAM and I'm at desktop.

I'll give this a try and let you know.
 
It is a BETA so this is expected but thanks!

I had mine crash for the first time ever last night. I had to force shutdown my system which I hate to do.
 
Its not beta. Its the demo. Beta was 2 weeks before early access demo was released to the pre orders from steam. Well I haven't played since 2-3 days ago so if there is an update for it recently then I will try it out see if it crashes.
 
Haven't had any crashes, in fact, it now uses all 4 of my cores as opposed to just 2 now. Exciting.
 
I just check out the demo again 8:35 a.m. Nov. 13th without a crash. I have a dual core but it uses up to four now thanks to foxhounds post! j/j hehe
