I'm getting this crash when I star the game also. I have attached my DxDiag and RPT file. I have tried updating drivers. Switching between experimental and stable. I have also attached my error.txt file. It keeps showing the same error in it also.

I get lots of stuttering too. Seems to happen more frequently if I zoom in or a zombie jumps into screen while in motion. Turning also.
I'm also running a 2500k@4.8GHz,8GB memory, GTX 680 and 250GB EVO SSD

Getting the same thing. Happens after about 15-30 mins of gameplay.

This is still happening on 0.46. A friend of mine shot a zombie about 15-20 meters away and I didn't hear the shot. I also died at NEAF to this.
