Just to give some background information. I was able to buy and install the game before the recent 06/01/2014 patch. Played up until the patch was released, about 8 hours or so. Logged in the next day, game updated and thus began the constant crashing.
What I've tried:
-reinstalling directx
-updating battleeye dll manually
-uninstalling and reinstalling dayz
-verifying game cache
-running with optimized launch commands
-running through task manager
-enabling/disabling beta testing
-defaulting to stock settings
-running without antivirus/firewall on
Rig information:
-Wins 7 SP1
-i7 740QM (1.73 ghz, 6mb l3 cache) [clocks to 2.99 ghz)
-Mobility Radeon HD 5850 3.8MB
-8 GB DDR3
