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.
I didn't try it, because I am not that curious about who's host.
This is not Bannable, But you need to set your config as ReadOnly or it can sometimes revert on SteamCloud Sync.
Another way is with the console command that displays FPS. It also displays the Host's ClientNumber, Witch is retriviable, But this gets more complex ( And Bannable ).
