This game does fuck you about a bit, i played this morning everything was fine, went out to do a bit of shopping, came back and played again 3 maps laggy as fuck, even getting to the point on one map where my screen was actually freezing for a second or two, how does this happen when everything was fine just two hours earlier, oh yes Deejay when you eventually find the sound options it does give you quite a few options to suit yo ie Headphone, Home Cinema etc etc, one setting i had it on called War tapes, made everything so loud the first explosion nearly knocked me off my chair,every sound seemed to be highlighted to the maximum,you could hear every tree rustle in the wind etc but it got so full on i couldn't concentrate so i went back to Headphones sound...but as for the sudden lag i have no explanation it really pisses me off about this game, one minute fine the next minute you can hardly play it.
