Problem using oculus DK2 with unreal engine

I am creating an oculus experience using oculus and unreal engine 4. But I have two problems :

  1. Unreal engine 4.4 dose not support oculus runtime 0.4.1
  2. and I am getting lot of lag in my game while using oculus

As someone who has a DK2 I noticed this missing feature at the last UE4 update: Unreal Engine 4.4 Released! - Unreal Engine Hope UE4 team will take care of that in next versions.
