Have you tried setting the extra latency mode to 0 and see its effect on tracking performance as well?

Just tried it; hard to tell with my simple test case if it improves with VRAPI_EXTRA_LATENCY_MODE_OFF ovr ON.. it still feels not as snappy as the oculus home controller tracking when switching back and forth (oculus home has extra latency activated according to OVR Metrics tool).
Do you have an Idea on how to better test/debug this?
The first time I noticed this was actually when I tested a small project (that ran perfectly smooth at 72 hz) and after 5min I got sick... which never happened to me with other quest apps so far even after >1hour...

I think I found at least one Issue with the controller tracking:

godot_oculus_mobile/src/ovr_mobile_controller.cpp

Line 147 in 3639380

if (vrapi_GetInputTrackingState(ovr, controller_state.remote_capabilities.Header.DeviceID, 0.0,

passes 0.0 as predicted display time instead of the value that is queried here

godot_oculus_mobile/src/ovr_mobile_session.cpp

Line 247 in 3639380

predicted_display_time = vrapi_GetPredictedDisplayTime(ovr, frame_index);

Passing this value on significantly improves the situation for the controller.
