    Hi folks,
    I am building a VR project in Unity where I want to collect eye-tracking data. I am using Tobii XR SDK for Unity to get the data from HTC Vive Pro Eye.
    I have some UI elements like a timer that has to be visible to the participant always. Hence, I have a two-camera system, where I have camera1 which has these UI elements, and camera2 which looks at a raw image with camera1's renderTexture. This system works fine if I don't have the Tobii software in my scene, but when I add it the scene becomes very jittery (laggy).
    I assume it is a performance issue but my resource utilization is around 50-60% with eye-tracking ON which is strange and points out that the assumption is not correct.
    Also, please let me know If anybody has a better way of showing UI elements in your scene that don't get occluded.

    Any help is appreciated. Thanks!

    I have the same problem as you. My scene is laggy when the Tobii software is activated and not when it is disabled. I currently have no clue how to fix this...

    Did you ever find a solution?
