Hi, this is my first post. I've been playing DayZ for a few months now and have also been playing arma 2. I can run arma 2 on max settings but on dayz I struggle to keep a steady frame rate on "high" settings. My computer specs are: Intel q6600 clocked @2.4ghz Sapphire hd6870 1gb Kingston 8gb ram Asrock mobo etc... Since both games are running on the same engine, why does dayz not run as well as Arma 2 does?
