After like 10 minutes of Playing Arma on a server i get a windows error message: "The exception "unknown software exception" (0x000001d) has occurred in the application at position 0x0000000001D0B4AA. Click "OK" to exit the program" (not 1:1, translated from german to english)
And after i click OK the Arma3Launcher come up with the errorlog and the errorcode: "STATUS_ILLEGAL_INSTRUCTION"
