Quick fix for this. Not my find but I can't find source so this is how to temp fix it. First close arma2 Go to your documents/arma2/ and find (Your user).ArmA2OAPROFILE and change scene complexity to 10000 Start up the game and if you still see visual errors change your vsync. Also this fix lowers your terrain details to very low so you may want to boost it up when you start the game. must do each time you start the game.
