In BFBC2 they've used Frosbite engine and they upgrade it for BF3 to Frosbite2 and it will use directx 11 as well.Imagine this quality in a full 64 players multiplayer with vehicles,tanks,apc,Jets,transport heli and Choppers.This game will be very hungry no doubt.I just hope they make it run smooth and they fixe high ping which they were unable to do with BFBC2 yet.
