I have to disable one of my display adapters to run games, and when I do, they run very poorly. I do this through Device manager > Display adapters and then either disable my Nvidia Geforce GTX 960m, or my Intel® HD Graphics 4600. when I disable either of them, my games can barely run. When I keep them enabled, they crash on launch. The games I am trying to play are COD BO2, GTA V, and World of Warcraft. I am on an ASUS laptop and I have run these games perfectly well before. Can anyone help/know whats going on? thanks in advance.
