TN issue / 2042 all of a sudden unplayable.

Over the last few days ive been playing bf2042, starting last night after i started up my computer i tried to play again and the performance has made the game unplayable. i cant hardly move, and sometimes it kicks me from the game saying i have been disconnected,  timeout, etc.

Prior to this I had 17  hours gameplay with no issues whatsoever.

My TN (time nudge?) is spiking up from as low as 20 to over 1300+

Any help??
