iL asked me to have a look at this so I made one.
Seems to work ok. My CPU usage shows 0 most of the time.
Have tried it in a couple of games with no lag.
Please test
-- edit --
Have made this 2 plugins. There is 'C' for Channel and 'G' for Game.
You can use either one or both of them. If anyone has problems using this in-game, they can use the 'C' only and give their CPU a rest between games, although I am having no problems using it.
Note: The "Game" starts in the pre-game lobby, everything else is "Channel".
