Wow good job you have it sorted! Some of us others are still crashing out regardless of drivers.

i think mine is ok - can play story mode fine not a problem
plays smooth as butter for me....except
i am getting loads of lag (hope its internet lag) running on the spot, i move then it puts me back to where i was etc
now will prob get shouted at, but i am playing over wireless to my BT Hub4 (infinity) do i really need to be connected via lan?

Being connected by lan will give you the best chance of a smooth gaming experience, if running a long cable isn't an option maybe something like these would work;

I use homeplugs, router is in living room and PC is in loft and they work fine, get full speed of my fibre connection through them![]()
To the op, glad you got it sorted and your right BF4 is a bit of a buggy mess at the minute but when it works it's beautiful![]()
