You could also try changing your rates in CSS, you will need to use the console for this, you can enable it by going to options > keyboard > advance, and then tick the box where it says "enable developer console" then click apply. After that the button under escape should open the console.
In the console type:
cl_cmdrate 100
cl_updaterate 100
rate 20000
Those are the rates i use, and all my clan members use aswell.
