Was on beer drinkers server just now myself, did it feel a bit laggy for you tom? Probably my crap connection isnt helping, definitely not a graphics issue as fps never dipped below 90.
Just left the sas server as well, cg's all round. And one bloke on our squad who insisted on staying on a rooftop trying to snipe, instead of attacking m-coms.
I reckon this is the first game in years that I would say I have an addiction to its like FPS crack.
Not sure what the appeal is but possibly because you can play the game in so many ways and every game is a just a bit different depending on whose playing.
