Battlefield 4 Very high packet loss on most servers (RecvRate drops to 20hz)

I have noticed that while on a server that was running at 60hz tick rate the down rate for the server was fairly low and when i had gone to a server running at 30hz it had a down rate at x3 the level of the other, i will need to check another server running at 60hz tick rate to see if it was just that one server with a slower downrate or if indeed it is all running at 60hz.

EDIT - Same server as last time but less players and it seemed better so possibly server not running optimal when full
