Hey Panzer,
I've seen this issue too in the past 1 or 2 weeks. I've got an ATI-gpu.
Tonite it happened again.
At the exact same time, one of my squad-buddies in the UK tried getting on the masterserverlist, but CTD'd as well after he logged in and was waiting for the list to appear.
Here's the crash-log :
Now, the funny thing is, about 1,5 hours after the crash, with nothing shut down or restarted on my computer (TIR still running), I can log in and see the masterserverlist no problem.
Here's the dcs.log
