Simple Movement in the Oculus Rift?

I've started to notice that the moment I put in the Oculus Asset, the game becomes impossibly slow. There is almost nothing in the game and yet it slows down an insane amount. Also, turning isn't the best. Movement is also laggy, and I can't even :D
Also I can't get jumping smooth.

I'm relatively new to the Rift SDK, can anyone help me with this? This sounds kind of like a latency issue but I'm not sure.
This is what I plan to do:

- to solve turning and looking lag, I want to create deadzones so that it only turns if the gyroscope experiences more than say 5 degrees of change

- to solve movement lag, I have no idea at all

- because jumping isn't smooth, I'm not going to use it at all


By the way, lag may seem like a simple issue, but my plans are for a large multiplayer horror game in which lag would pose a very serious issue to gameplay.
