[VR.WaitFo] Slow FPS and Slow Input axis reaction time lag using joystick or pad and VR occulus rift

Hi there @thep3000 @Ed-unity my joystick has a reaction delay of 1 second. It works properly, If I turn off my VR Oculus rift the joystick and axis input work correctly. In editor and in the game. I'm using Unity 5.5.3
Looks like there is a relationship with FPS.
Any idea how to resolve this problem?

 

I jump from 5 fps up to 60, just changing "Shadow Cascades" form non-cascades to 2 cascades.
@thep3000 @Ed-unity Is there a way to exclude VR.WaitForGPU out from the process?

I'm too new to programming to do this kind of major clean up. I was looking here:
SteamVr HTC Vive weird FPS issue

I wish a code in C# for Oculus that takes out VR.WaitForGPU

None Cascades 5fps


Two Cascades 60fps
