Battle field 3

BF 3 is a very CPU demanding game just as much as it is GPU demanding and it's fully optimized for 4 or more cores.A dual core is the bare minimum for the game to run.It seriously won't even start on a single core.Every benchmark I've seen has all of the dual cores completely maxed out.With such a low resolution it will require the CPU to do even more work.You can definity play the game but you won't max it out.

Is that your monitors native resolution?
