really struggle to get more than a 2 bar connection on this game, and only this game. all other fps mp are fine.

Exactly.

Black Ops, Battlefield Bad Company 2, Halo Reach, Homefront - All work fine without the lag.

Crysis 2 however, now due to the shambolic Network Coding makes it annoying to say the least.

CRYTEK - YOU SAY YOU ARE PATCHING THE GAME, DON'T YOU DARE SH*T ON US
