So I recently purchased arma II and have downloaded the dayz mod for it, installation and everything else was fine but when I joined a server I found that I had a huge amount of lag the game was completely unplayable, I tried going onto different servers but it was the same problem so I figured it was something to do with my pc It is a hp a6550a Processor: intel® core duo CPU. E7200 2.53GHz And the graphics chip was pre installed I think but is a NVIDIA GeForce 9300GE. Also I have 3gbs of ram. I was just wondering wether it was the pc, the graphics chip or something else that is making it so laggy, this also happens on other demanding games such as skyrim Thanks :)
