Hi all, I received my 8KX from Amazon yesterday and while I feel the headset has a lot of potential, I’m feeling especially disappointed by the jittering when using the 8KX.
I’ll preface this by saying that I’m upgrading from a Valve Index, and everything works perfectly with no perceptable jitter. I also have a Vive Pro 2 for over a week and that also had no jitter what-so-ever in my setup.
My 8KX headset has quite noticeable jitter and I’m also getting jitter on my Index Controllers when they are paired to the 8KX (but they’re fine when paired to the Valve Index).
Can some others run this jitter tester and tell me their results?
Just put your headset down on a solid surface with visibility to your basestations and press the space bar. It will record how much your headset is jittering and give you some numbers.
Here are my results with my VALVE INDEX:
- Max Deviation (Position): 0.32
- Standard Deviation (Position): 0.07
- Max Deviation (Rotation) 0.03
I can run the test multiple times and pretty much get the same exact result every time. There’s no perceptible jitter with my Valve Index.
Here are my results with the PIMAX 8KX:
- Max Deviation (Position): 2.64
- Standard Deviation (Position): 0.58
- Max Deviation (Rotation) 0.25
As you can see, these results are massively worse, and running the test multiple times gets pretty different results each time (almost always worse). As I said, my Index Controllers also jitter massively when paired to my 8KX and sometimes fly off in the distance. This never happens on my Index.
If I disable lighthouse tracking in Pitool and use 9-axis, the jitter is almost as good as my Valve Index results, so the 8KX headset isn’t inherently jittering, only when tracking with the lighthouses. But at the same time both my Valve Index and Vive Pro 2 work perfect when using the lighthouses.
I’m using the latest Pitool version and I’ve tried the latest headset firmware and beta headset firmware (for 90hz Native w/ my RTX3080).
I had packed everything up and submitted a refund request to Amazon, as I was assuming this is just expected behaviour of the 8KX. But I REALLY like the wider FOV and massive resolution of the 8KX so I’m hoping after comparing to other people’s results, it’ll be obvious that my 8KX is simply faulty and I should get a replacement from Amazon instead of a refund.
