Before you do this make sure you have the recommended settings already:
rate 100000;cl_updaterate 101;cl_cmdrate 105;ex_interp 0
Note that your cl_cmdrate should always be atleast 5 more than your fps_max.
You can copy and paste the whole string of commands above and paste it in the console.
1. Join a server and type "net_graph 1" in console
2. If you see red dots at the bottom of the graph, raise your cl_cmdrate until they're gone.
3. If you see yellow/orange dots on the graph, lower your cl_updaterate until they're gone.
4. You always finish by entering ex_interp 0 (very important).
5. Done! :)
If you want to easily change rates when you switch servers without having to type all of these commands in the console, download my customized command menu:
