When using a Vive in 2018.2.0b5 and b4 I've noticed that there's a severe delay in moving your head and having the screen react to your movement. I've noticed this in our project where we use TrackedPoseDriver, but using the SteamVR tracked object for the headset does not solve the issue. The only thing that has solved the issue is to use the Camera by itself with no TrackedPoseDriver or SteamVR components attached to it. The problem is incredibly easy to reproduce. Steps to reproduce: Open any project, or start a new project using Unity Hub, selecting "3D with extras" or "[XR] VR Lightweight RP" Open the SampleScene Add a Tracked Pose Driver to the camera (important) Turn on VR in Player settings, make sure OpenVR is in the list Hit Play Put on Vive headset and move your head around, notice the delay in the visuals To solve temporarily: Exit playmode Remove any Tracked Pose Driver or SteamVR components from your camera Hit play Notice no delay This is a straight regression from 2017 and 2018.1 into 2018.2 Setting "Update Type" to any value does not change the behavior.
