Same problem on my Sapphire HD 7870 graphic card. Game crashes like every 10 minutes randomly while playing in multiplayer. Did not have this problem in Alpha version.
AMD Catalyst driver: 13.6 (package: 13.101-130604a-158071E-ATI, beta!)
Crash report + dxdiag in attachment.

Regards.

In regards to that last comment by Rnd, I'm just informing that my driver package is 13.4 using the "AMD VISION Engine Control Center version 2012-1219-1521-27485"

Just bumping to see what is going on about this issue.
Are users still crashing? I haven't played the game in a while.

This is happening to me constantly also anywhere between a few minutes to half an hour after loading in in, Making the Game VERY hard to play, Muddles everything up and destroys what I'm doing on Capture the Island Warefare Benny edition every time I have to reconnect.

Radeon 7770 GHZ edition, Windows 7
