Theres always been 2 types of black outs, I think that your just seeing the other one now since the update, have you d/l the new high res pack?
The 2 types of blackouts in the game are, the first is the whole screen slowly goes to black, the 2nd is the black out starts at the edges of the screen and slowly closes in on the center of the screen. So are you seeing something other then one of these?
