Tried some random servers all are the same.
My system - q6600 @ stock, 4870, 4gb ram. Slightly ageing but I play most new games fine with some settings lowered but with bf3 I am literally using the lowest possible settings. And it still lags.
For example I play bc2 fine maxed out, even being able to use 1x anti aliasing and its like silk.
I don't think I'm over estimating my pc's capabilities? Its just a poorly optimized game.
The connection dropping out might be down to my router which I've had issues with before so I'll give them the benefit of the doubt on that one.
"A lot of the lag issues have been sorted", **** looks like I face a unwanted graphics upgrade
Caspian Border is quite smooth but just played sehne crossing and it was lagging horribly.
