I haven't tried the latest Oculus SDK, but the problem you are
describing is most likely due to your implementation of the video
streaming than the Oculus SDK. I doubt they would release code that is
THAT broken, especially when they go to the trouble of having custom
functionality built into the Nvidia driver to squeeze down the latency
even more.

How much latency has the RealSense camera itself?
