Try setting your rates on Steam and in-game. For high speed connections, use updaterate 101, cmdrate 101 & rate 25000 (those values could've changed due to engine updates), or goto steam>settings>internet connection and select your connection speed. Verify your connection speed by going to www.speakeasy.net and running a speed test. Use this as a guideline as to what connection speed to set. If you are experiencing lower speeds than normal, contact your ISP and have them trouble shoot the issue with you.
