Now with the BETA, if you use a RCO scope, it's almost easier to see something outside of the scope than inside because of the glass effect inside the scope. It's definitely not logical... :(

This is ARMA3, a realistic game, not COD or Battlefield, so vote up!

This is really annoying, sometimes you cannot see your opponent due to the rain or darkness while he can easily spot you because it's sunny on his side...
In the same way, when the weather is stormy, lightings should be synchronised for all clients.
