Welcome to the forum. 
Not sure if you’re jesting, but Grim Dawn isn’t a speedy game like PoE. If you want that, then that’s the game you should play. GD is more exploration, finding all the little hidden secrets the game has to offer and making more characters than you know what to do with.
If you’re really desperate to rush about then use the Grim Internals tool. I think it has an option in it to increase speed.
