changing resolution during the game

Blitz3D Forums/Blitz3D Programming/changing resolution during the game

how to change it during the game?
"graphics3D" command return an error if it is used after any other 3D command... But i have seen some B3D games with this function (Mr Twinkle).

So how to change this resolution during the game, and not before in any config program (......made with Blitz +) ?
