I've been having a strange problem since i got my touches in, whenever im using more then one sensor my hmd tracking jumps when turning around with my back to the cameras.
I dont run into this when using just one sensor. I can turn around and the tracking is 100% solid, but the moment i plug sensor two back in the tracking jumps when i stop with my back to my sensors. This shouldnt be happening with the hmd I would understand if it was the controllers but the Rift has tracking lights on the back of it.
I've tried using every combination of usb ports and sensor placement, from up high on the ceiling to just on my desk still the problem remains. I even borrowed one of my buddies cameras to run the experimental setup, the irony is that the controllers track great with the three cams in roomscale but the hmd does not. Playing something like jobsim on steam I will turn around to grab something and the whole world shakes like someone is bumping my sensor.
I've spent the last two days trying everything I can think of but still nothing helps other then using just one sensor. The last thing I can think of trying is buying a usb card and see if that helps. Sorry for the wall of text but I've been beating my head against the wall trying to smooth out the hmd tracking just a little frustrated at this point.
