Controller Tracking Performance in UnityBuild different to Editors Performance

Hi!
I'm doing a first practice project in VR ( Oculus Rift S ) with Unity 2019.2.6.
Using the awesome VRTK asset for player-control ( just looking around ) and interactions ( grabbing models ). While running the project within the Editor the performance is very good, smooth movements etc.
But when running the build app ( WIN64 ) there is a perceptible difference to the editor performance - movements are pretty jerking.
There is a jerking performance even when only the main menu UI is active ( based on VRTK Tooltip heading to camera )
Is this a common thing? Would be thankful for every hint

UDATE:
I think it's controller tracking. Got a simple boxes attached the right / left hand anchors and when moving the controllers around -> the update is very choppy in the build version.
Do i have to set up frame rates ? Or is it possible to set the "refresh rate" of the controllers position ?
