It seems there are versions of this laptop with and without discrete graphics. If your unit doesnt come with the GeForce 920MX, you coud change your CPU for onde with Intel Iris Graphics, which would be a huge jump in performance. If yous come with the 920MX, you could open it (it voids your warranty) to see if its soldered or comes on a MXM module. If so, you could probably exchange with a Geforce MX150 MXM module. But either way its not a easy, error free process...
