Hey guys, recently got Arma II, and the dayZ mod and thought my computer could run it, except the graphics which was causing alot of lag even running on really low, I have updated to a Radeon HD 6450 which is enough I think for normal graphics and play has become more fluent but every now and then it keeps lagging sometimes for a second or two and sometimes more like 10 seconds and its really annoying at first I thought it was the server, but it happened on any server im on and people I have talked to have said they dont recieve lag and ive watched videos on youtube where people arn't lagging. So im assuming its either my CPU or Ram needs upgrading ideally both but which would be the most affective one now? I currently have 2GB ram, and AMD Athlon 64 x 2 5200+ @ 2.7ghz any suggestions? any help would be much apprecieted :)
