My problem isn't as bad as yours. I'm in uk and it seems to do this when I join a uk server but fine when im in a US or German server. My ISP seen no problems and neither did my server host nitrado. Hopefully if its with bohemia, they can look into it and get the problem sorted. There's a few threads here with the same problem.

Same issue with VM and Vodafone. I connected to German and American servers and so far no bug.

Hey which ISP do you use? Which hosting location does the server use?

Hey I have this same issue. Which ISP do you use? Where is the server hosting location? London?
