I’ve been testing the tundra trackers for a week (3 + SW3, firmware up to date, roles assigned). That there were issues was immediately apparent, but I’ve performed thorough testing and I can’t figure out where exactly the problem lies (there might be multiple). I can’t isolate any specific faulty component (unless it’s the SW3?) Maybe someone here can help me clear this up.
I have a current gen desktop PC (750w PSU, 3070ti, Ryzen 7 5800x), an HTC Vive, Index controllers and base stations v1.
Issues observed: Trackers wobble a little in incorrect directions when moving or even if they have been standing still for just a little while. If I haven’t been moving for a longer period of time they can disappear completely. Shortly after turning on or after they’ve been on for a more extended while they can jitter violently and disappear or look like they’re flying off into the distance. This never happens to all trackers at the same time. It seems to happen to interchangeable trackers on a per session basis. So far, if I’m wearing the trackers, the most stable tracker is always one of the feet (but I’ve swapped them). If the tracker has disappeared from the playspace, it won’t reappear until I’ve moved it quite a ways away from the position where it disappeared (after which I can go back to that position). Keep in mind these are not stable issues but they happen over time (reliably as long as I play long enough).
In the same playspace, the Index controllers and headset do not experience any tracking issues and are always rock stable and appearing where they’re supposed to be.
In addition to several hours of practical testing in VRChat, I’ve tested in “ideal” conditions by placing the trackers on a flat table right in the middle of my playspace, equidistant, with the index controllers beside them for reference and both of the base stations pointing directly at them. I’ve tried placing the trackers on their base and on their sides. I’ve moved around the table to ensure I wasn’t blocking anything. The Tundra trackers jittered, disappeared or were offset from their supposed positions while the Index controllers around them tracked properly.
I don’t know if it’s normal, but just passing my hand over the trackers while they’re on the table without touching them is enough to make them wobble a bit (the index controllers are fine).
I readjusted the aim of the base stations, redid room setup, used the steamvr button provided for the purpose to disable USB power management, none of which has helped (but the headset and controllers kept tracking properly). I’ve tripled checked there were no reflective surfaces in the room. My smartphone was removed. The windows were covered.
I’ve tried USB2 and USB3 ports for the dongle. I’ve tried the extension cable and a HTC weighted base. I’ve tried USB ports from my motherboard, from my computer case and through a USB extension card with dedicated power. I’ve tried placing the SW3 horizontally and vertically where applicable (including using the extension cable).
So. What exactly is going on here? Is there an issue with my computer or playspace that I can deal with myself in order to solve this problem? (If you’re an experienced full body use please try to remember if there’s anything and let me know, since it would be much easier than getting an RMA.) Or is the dongle broken? Or every tracker? Maybe everything at once? It does look like there might be more than one issue here…
