Oculus Rift Direct Mode Crash

I’ve been trying numerous ways, but no matter what I do, UE4.5 or 4.6 crashes in Direct mode. It crashes on any UE4 .exe (either mine or from the Oculus share), and it crashes when I open the UE4 editor:

I have a DK2 and am using an Asus Repulic of Gamers laptop with an GeForce 880m, 24gigs and an i7 and am using Windows 8.1 with the latest GeForce drivers.

It works in extended mode but am looking for the performance gains from direct mode.

Thanks,

Hi ,

We noticed that this is a duplicate post of this question: UE4 crashes in OR Direct mode - XR Development - Epic Developer Community Forums

We will be closing this post in order to focus the discussion in one place.

Thanks,
