The trackers connect to SteamVR and are tracked on the out window, but not seen in VR

Only one tracker may show in VR, while the others are marked as inactive on the status window. This is a known issue with additional smoothing: set it to 0 and it should work again.

If you really need additional smoothing, you can download MediaPipePose from my repositories, uninstall the driver and install the one that comes with it. It comes with a newer version of the driver, where this issue should be less common.

The trackers lose tracking during movement

This is caused by motion blur of the camera. When a tracker moves, its edges get blurred, which causes detection to fail. To prevent this, you need to reduce the exposure of the camera. Refer to the Connecting a camera page for more detailed instructions.

The trackers have huge (around 1 second) delay

Refer to the The trackers lose tracking during movement issue above. Since trackers arent detected while moving, and will only be redetected when you stop, it will feel like they have huge delay.
