And Day-Z will be a standalone based on the engine used in Arma 2 I believe, but it will have more stuff added that is seen in the Arma 3 Alpha.
I do hope they fix those "non-optimizations" for the beta and full-game. Its ok if it is plagued with problems, as long as it shows great potential and realistic physics/graphics from their game engine, it can be promising. Remember it is only an alpha. And an alpha is far away from the quality of the actual game.
