Again, not sure if this is a result of the upgrade work, but for the most part, i can now actually enjoy a game at some point after midnight.
I played Black Ops for the first time in a year and enjoyed a portion of it, although i was having little jumps of lag every now and then, which may or may not have been due to a rubbish host.
FIFA is still touch and go, but during the times of minimal jitter ive been able to actually play the game without wanting to post Anthrax to Virgin Media's headquarters.
