Yea but since arma 2 isnt optimized for the new pc technology it will not run right, and dont forget it is an old game, although i do remember when i played arma 2 a year ago it didnt lag at all for me, but further made it lag. And the ai script is the killer here, it is not simple it is very complex and not very how should i say this... not very put together write so they bug out our machines. it is mostly the ai. oh and when you said that your older setup worked better then new it is because arma 2 will work better on different rigs then on others, even if your new one is more expensive, certain graphics cards and processors work better together then others if you get what i mean
