Long story short, have a laptop. GT650m and HD4000 (integrated). When playing rust, it uses only hd4000. All my attempts to make it use GT were futile. Even downloaded chrome, enabled gpu acceleration to no avail. I bet there are lots of peeps here knowing more stuff about computers than i do, so the question is: how can i make the game/unity player use my GT650 not integrated card, if its possible?
