So here it goes,
my buddy @Garrus-Vakarian recently has this weird issue where the game just becomes completely unresponsive and hangs after about 20-25 minutes. "Hang" in this case means that Windows says that the application has become unresponsive and a white overlay is put over the app. Meanwhile the game stops for the rest of the players but nobody gets displayed the disconnect window until he kills the process. The process uses 100% of a single CPU core while hanging.
We used WinDbg to create 4 consecutive memory dumps of the game while it was hanging I hope you can do something with that.
