I have the same year laptop. Turning the detail all the way down, diasble all eye candy,visual range ,and using gamebooster. I'm able to get frame rates of 40 when not around anyone. To frame rate of 2 when fighting. Flying a plane I'm like joeblack, out there yet not benefiting me in anyway. I remember shooting tanks and watching them blow up 2 minutes later.
Welcome back ,sayonara,and see you real soon.
