The big diffrence between Rift and Vive is the software... Rift got a software, that counteracts the missing frames, and therfor the jitter... "dont aske how its done, but it works.
I dident mean to sound arrogrant, I am just wondring why, so many got these problems, and my set up dosent. What I do know is, when Runtime 1.3 from Oculus was released, with its new software, I got rid of the jitter and my frame rate went up.
