Left 4 Dead Message Board  

No matter what level, character, weapons, ect I choose, L4D runs fine for just about 60 seconds, then crashes to desktop with no error message. This happens whether I use the trainer, cheats, both, or neither.

Wtf?

Anyone else having this problem?

This is not a driver issue, I just installed the latest ones about ten minutes ago.

Well, got a few fixes. Apparently there are some issues with the game automatically multi-threading, which causes serious instability. This can be disabled by opening the console and typing "mat_queue_mode 0" without quotes. Also, enabling vSync causes instability issues.

There is an option in the video -> advanced settings, called "multi-core rendering" which could be another word for "multi-threading" so try and turn that off.

I am having the same problem.. Even with the "multi-core rendering" on or off..

Pretty strange..

Im running Vista Home Premium 64bit. QuadCore Q9450 and a 9800GTX..

Any ideas..?

Thanks

ok think i found the fix.

what worked for me was to
disable the multicore
switch vsync off
play in window full screen mode

either one or a combination of these works.


good luck.

enter mat_queue_mode 0 in the console, so it'd only work on ONE core.

it could also be heat a friend of mine had it keep crashing on a AMD dual core. I installed a much more powerfull custom fan and heat sink and all the crashes went away. so I would say try cleaning the dust out of your heat sinks with compressed air and see if it helps. it just seams the game is alot more CPU intensive than other games.
