I have an old system but it actually plays quite well when I am in the game, I can't complain.
But It takes about 5 minutes to get into the game if it starts first time, usually not. Then I have to select weapon and gadgets etc another couple of minutes, I hate having to click on all the menus and sub menus to get what I want.
I went back and played BC2 and was on a server less than 1 minute including the loadout. BC2 load out screen is so much better, everything there visually on the screen, no searching for items.
It is a real hassle starting up this game.
