I have a Steam app called Controller Companion which works well. If it costs anything, it's extremely cheap. I've used it for the old versions of the Tomb Raider Steam releases as well as RPG Maker fangames.
Game looks outstanding from what I've seen. One thing I think could be improved on the options menu is the game actually telling you the specific of what each setting does, it's a bit confusing to differentiate what some settings do.
