I get "connection to server has been lost" quite often. seems like it mostly happens when i am doing really well and get mvp a bunch of times in a row. but when i dont do so well i never lose connection.
if i am not paranoid and this is a known problem, is there a console command to improve it? or do i need to stop being so badass that people kick me from their servers?

It affects a lot of people and there is no fix for it at this time. Crytek has taken note of the program and supposedly working on a fix. Just gotta be patient.
