My SteamVR navigation seems to be playing up. The Oculus system is fine, no issues, When I load a SteamVR game (Project Cars), it also works great with no issues.
Its just jumpy, and constantly loading (don't know why).
Project Cars has native Oculus support, that is why you have no problems with the game. I only use Steam VR when absolutely necessary. VTOL & Onward. I doubt that I will be buying another game that does not have native Rift support.
