Hi,

I am also experiencing the same thing, but my scenario is a bit different. The game will start off normal, then halfway will have lagging issue ( i can confirm that it is not network connection as i am in the same game with my bro, his game is fine) and then after that my lappie will have BSOD. Last week it was still fine, only this few days it started to have problems.

here is my spec:
-win 8.1 64bit
-intel i5-4210u
-8gb ram
-Nvidia GeForce 820m
