Idk if this works for PC but on the xbox I use this:
I take no credits for this!
This is an edit you can do to your config to show more detailed connection information.
I don't think this is VAC Bannable.
Navigate to the folder
"program files\steam\steamapps\common\call of duty modern warfare 2\players"
Open the file config_mp.cfg in .txt
Use Ctrl + F to find "scoresping_interval" & "maxbars" (without "")
Change "scoresping_interval" from 100 to 20 and "maxbars" from 4 to 10 (10 is the max).
This means that each of the 10 bars represents 20ms, with full green being 20ms or lower, and 1 red being 200ms or higher.
Hopefully it will work.
