UE4 4.10 and nvidia K3100M 4 GB gpu for oculus VR

my oculus (using 0.8 oculus runtime) works well enough for my needs with this gpu - i can do the oculus demos fine, but when i use UE4.10>play>VRpreview it pops up a black screen. in the oculus i can see the health warning disclaimer but everything else is black. is there anyway to get UE4.10 to work with this gpu? will it work with UE4.11?.

this is a laptop and that’s the highest end gpu i could put in it

thanks
